Defendant was convicted by jury verdict of possession of narcotics and sentenced to serve a term of one and one-half to ten years in the state prison. MCLA 335.153; MSA 18.1123. From this conviction defendant appeals, raising six *534allegations of error: (1) the prosecution failed to prove lack of license as a necessary element of the offense charged, (2) the prosecution failed to submit sufficient evidence, of due diligence to justify the nonproduction of a res gestae witness, (3) the trial judge refused to suppress a package of heroin as the fruits of an illegal arrest, (4) the trial judge failed to permit defendant’s cross-examination upon the police officer’s intent to arrest him, (5) the trial judge erroneously instructed the jury that reasonable doubt may not be based upon the lack of, or unsatisfactory nature of, the evidence, and (6) the trial judge erroneously instructed the jury that any quantity of narcotics was sufficient to support a conviction.

On March 5, 1971, the Detroit Police Department received an anonymous telephone call stating that Eugene Harris would be in possession of narcotics. The anonymous call provided the police with a description of Harris and the location from which he would be leaving. Several officers were dispatched to the described location and observed two men, one matching the given description, enter a red car parked near the curb. The officers pulled alongside the red car in an unmarked police vehicle, displayed identification, and announced that they were police officers who "would like to talk to you”. While exiting their vehicle, one of the officers observed defendant pick up a foil package from the front seat and throw it out the window. This officer retrieved the package approximately one foot in front of the car and examined its contents. Suspecting it to contain a quantity of narcotics, he arrested defendant. Defendant was subsequently tried for the unlicensed possession of narcotics and found guilty by jury verdict.

I. Did the prosecution’s failure to prove lack of *535license as a necessary element of the offense charged require a reversal of defendant's conviction?

Recently the Michigan Supreme Court in People v Rios, 386 Mich 172 (1971), held that (1) lack of license was a necessary element of the crime of unlawfully selling narcotics and (2) the burden of proving lack of license fell upon the prosecution. This holding has been extended to cases involving the possession of narcotics. People v Gould, 40 Mich App 689 (1972); People v Maceri, 39 Mich App 38 (1972); People v Edwards, 37 Mich App 490 (1972).1 The prosecution’s admitted failure to prove lack of license requires our reversal.

The remaining question to be answered is whether this error requires an outright reversal of defendant’s conviction or a reversal accompanied by a remand for new trial. This Court’s disposition of errors based upon Rios includes both approaches. The defendant’s conviction was reversed without remand in People v Gould, supra. Conversely, the defendant’s conviction in People v Edwards, supra, was reversed and remanded for a new trial. The Supreme Court’s disposition evidences similar inconsistency. The defendant’s conviction in People v Rios, supra, was reversed without direction for remand. However, in subsequent cases whose reversal is based upon Rios, the Michigan Supreme Court has specifically directed a remand to the court in which the case originated for a new trial.2 After considering the various policy considerations involved in the type of error at issue, we follow the Supreme Court’s most recent decisions and direct a remand to the De*536troit Recorder’s Court for a new trial. Finding several of defendant’s remaining allegations of error to be meritorious, we offer the following discussion to prevent their repetition upon remand.

II. Did the prosecution submit sufficient evidence of due diligence to justify the nonproduction of a res gestae witness?

The question of the people’s "due diligence” was submitted by the trial judge to the jury for resolution. Although such questions are generally decided by the trial judge, such disposition by the jury is a proper alternative method. People v Stephen, 31 Mich App 604 (1971); People v Howard, 24 Mich App 328 (1970); People v Kern, 6 Mich App 406 (1967).3 But let us caution that this approach presupposes the existence of sufficient evidence upon the claim of "due diligence” to justify sending the question to it. Defendant’s challenge is predicated upon a total absence of such evidence.

Defendant challenged the prosecution’s failure to produce the driver of the car who was arrested with defendant. The testimony offered by the prosecution to establish a diligent effort to produce this res gestae witness at trial is conspicuously inadequate. Although the testifying officer thought that a subpoena was issued, he did not know if it was served and the absence of its return in the court file led him to assume that it had not been served. The efforts to secure the attendance of this witness were not begun until the day of trial. Officers were *537sent to the address of the witness provided at the time of arrest and found it vacant. Subsequently, the desk clerk at the Wayne County Jail was contacted to determine whether the witness was presently incarcerated. The people’s efforts were concluded by a telephone call to the Detroit Police Department’s identification bureau to determine whether the witness was previously or presently in custody.

A positive burden to produce all res gestae witnesses is imposed upon the people to protect defendant from false accusations and preserve his presumption of innocence. People v Kayne, 268 Mich 186 (1934); People v Russell, 27 Mich App 654 (1970); People v Dickinson, 2 Mich App 646 (1966). Our close scrutiny of the people’s reliance upon the concept of due diligence to excuse such production guarantees the integrity of our judicial system. In People v O’Dell, 10 Mich App 87, 94-95 (1968), the Court found that "mere service of a subpoena does not constitute due diligence”, stating:

"The prosecutor must not only issue subpoenas, but he must also use 'other means at hand’ to produce endorsed witnesses.”

The present case fails to satisfy this language since the record neither provides evidence of the service of a subpoena or the bona fide use of "other means at hand”. More recent rulings of this Court relying upon Barber v. Page, 390 US 719; 88 S Ct 1318; 20 L Ed 2d 255 (1968), would measure the prosecution’s efforts to produce a res gestae witness by its "good faith”. People v Herman Brown, 38 Mich App 69, 74 (1972); People v Hairston, 37 Mich App 65, 74 (1971). The present inadequate and untimely effort by the prosecution *538to locate the witness at the day of trial cannot satisfy this "good-faith” standard.4 In this absence of any evidence substantiating the people’s diligent or good-faith effort to produce the only non-policeman eyewitness, the trial judge committed reversible error by submitting the question of "due diligence” to the jury.5

III. Did the trial judge err in refusing to suppress a package of heroin as the fruits of an illegal arrest?

This alleged error is based upon a claim that defendant was arrested in the absence of probable cause at the time he was confronted by the police officers. The concept of arrest pursued by the courts of this state flows from the following definition adopted from 4 Am Jur, Arrest, § 2, p 5:

" 'An arrest is the taking, seizing, or detaining of the person of another, either by touching or putting hands on him, or by any act which indicates an intention to take him into custody and subjects the person arrested to the actual control and will of the person making the arrest. The act relied upon as constituting an arrest must have been performed with the intent to effect an arrest and must have been so understood by the party *539arrested.’ ” People v Gonzales, 356 Mich 247, 253 (1959).6

The police officers in the present case pulled alongside the car in which defendant was a passenger stating we "would like to talk to you”. The officers’ conduct clearly restrained defendant’s freedom of movement and may be deemed a seizure, which is a primary element of an arrest. However, the degree, type, and purpose of the restraint will determine whether the conduct at issue constituted an arrest requiring the existence of probable cause.

The Supreme Court in Terry v Ohio, 392 US 1; 88 S Ct 1868; 20 L Ed 2d 889 (1968), recognized that not every restraint of a . citizen by a police officer constitutes an arrest. This principle was based upon the policy consideration that the police investigatory process is an indispensable function which necessarily outweighs minor intrusions into a person’s right of privacy. It is this investigatory process which constitutes the "stop” portion of the Terry Court’s "stop and frisk” rule and is distinguished from an arrest dependent upon the existence of probable cause. Case law interpreting this rule has further articulated its application to investigatory detentions. In Youngblood v State, 47 Ala App 571; 258 So 2d 913 (1972), the Court recognized a police officer’s right to stop a vehicle to investigate information supplied regarding criminal activity.7 The Court in United States v James, 147 App DC 43; 452 F2d 1375 (1971), was confronted with circumstances analogous to the pres*540ent case. There the police received information from an informant that two men would leave a specific address with narcotics. The police proceeded to the described address and observed two men enter a taxi. After stopping the taxi they requested the driver to produce his license and registration and step out of the vehicle. During this process the defendant-passenger pointed a weapon at the officer but was arrested. The James court rejected defendant’s challenge to his conviction of assault with a dangerous weapon because his arrest was not supported by probable cause. The James court reaffirmed the police officers’ right to stop persons for investigatory purposes, indicating that the failure to do so would have been a clear dereliction of their duties.

We find the police conduct in the instant case to fall within the purview of these authorities. They possessed information describing the defendant’s involvement in criminal activity, his appearance and location. This information was sufficient to justify defendant’s restraint for investigatory purposes short of an arrest.8 People v Bommarito, 25 Mich App 668 (1970); People v Wade, 23 Mich App. 132 (1970). The officers’ simple request to talk to defendant did not exceed this investigatory stage and cannot be deemed an arrest.9 Since the officers had a right to stop defendant for questioning, the narcotics thrown out of the window were in "plain view” and admissible at trial. People v Tisi, 384 Mich 214 (1970). The trial judge correctly ruled *541upon this matter and defendant’s allegation is devoid of merit.

IV. Did the trial judge err in failing to permit defendant’s cross-examination upon the police officers’ intent to arrest him?

The officers’ intention is a significant factor to be considered in determining whether a particular accosting is an arrest. Bonkowski v Arlan’s Department Store, 383 Mich 90 (1970); People v Gonzales, supra. In this event, the defendant would clearly have a right to cross-examine the officer with regard to his intention. However, our prior discussion indicates that the present case does not involve circumstances in which an allegation of arrest could be argued. The trial judge properly refused to consider the question of intention since the facts reveal a valid investigatory "stop”.

V. Did the trial judge erroneously instruct the jury that reasonable doubt may not be based upon the lack or unsatisfactory nature of the evidence?

In People v Davies, 34 Mich App 19 (1971), we considered a substantially similar jury instruction and found it erroneous. As in Davies, the present defendant did not object to the instruction as given and reversal of his conviction is based upon other grounds. Our acknowledgment of Davies is offered to prevent a repetition of its error upon retrial.

VI. Did the trial judge erroneously instruct the jury that any quantity of narcotics was sufficient to support a conviction?

The error of this charge was recognized by the Court in People v Harrington, 33 Mich App 548 (1971). The Harrington Court enumerated a new rule governing this area by holding that a conviction for the possession of narcotics could be sup*542ported if the amount of heroin discovered could reasonably be inferred to be "a remnant of a larger, usable amount”. Applying this rule to the "minute residue of heroin” discovered, the Harrington Court reversed the defendant’s conviction. The quantity discovered in the present case totaled 24 grains of bulk heroin. We find that this amount satisfies the Harrington standard and falls within the purview of the more recent case of People v Jones, 38 Mich App 512 (1972). Since the present quantity of heroin was clearly a usable amount, the jury instruction given below did not constitute reversible error. Repetition of this instruction should be avoided upon remand.

Defendant’s conviction is reversed and the case remanded for a new trial consistent with this opinion.

Reversed and remanded.

(concurring). I concur with the majority opinion in Part I, and agree that a reversal with a remand for a new trial is required.

I disagree with Part V and find no error in the trial judge’s instructions.
