The plaintiff, a minor suing by his next friend, brought this action against the defendants, who are the receivers of the Missouri, Kansas & Texas Railway Company, to recover damages for the loss of an arm. The chief complaints made in this court, are, first: that there is no evidence of negligence on the part of McMahan; second, if McMahan was guilty of negligence the defendants are not liable because he was acting in the capacity of a police officer.

The evidence bearing on the first complaint is in substance this: The yards of the railroad company extend from Third to Eleventh streets in the city of Sedalia. Various repair shops are located therein, and .a large number of men are engaged in the shops .and yards in repairing disabled cars. The main and several side or switch tracks run north and south through the yards. Broadway or Eighth street runs east and west *602and crosses the yards. John McMahan was employed by defendant as day watchman at and for a long time prior to the accident, and it was his duty to keep boys ont of the yards and away from the cars. While standing in Broadway near the place where the tracks cross that street, he saw the plaintiff and three or four other boys hanging to the cars of a freight train going south. It seems the plaintiff and the other boys got on the cars at the north end of the yards. Some of the witnesses say the train was moving at the rate of ten miles per hour, but other evidence tends to show that it was moving at a much less rate of speed. McMahan stepped forward so the train would pass close to him. ' All the boys except the plaintiff saw him and at once jumped down and ran away. The plaintiff had one foot on the lower step of a ladder attached to the front end of a car, and held on by grasping the upper rounds with his face to the car. The proof is all to the effect that he did not see McMahan and that the latter gave the boy no warning. McMahan had but one arm. The witness Brown who saw the whole transaction testified: McMahan got his arm partly around the boy, not clear around him, but just far enough to jerk him loose; the boy fell down under the car; McMahan made a grab for him and got him up when he fell back; McMahan made a second attempt to get the boy but did not get him in time to save his arm. Several other witnesses testified that McMahan jerked the boy loose as the cars passed and that the boy fell or was knocked under the car. McMahan testified as follows: “When- the boy got close to me he let loose and jumped off and in doing so struck me; the force of the moving car threw him against me as he fell; I attempted to catch him but he twisted around and fell; the axle of the wheels.struck him and turned him over, and I made a second grab *603for him; the front wheel of the back truck ran over his arm.”

A city ordinance read in evidence made it a misdemeanor for a boy under the age of eighteen years to' hang to a moving car. The boy testified that he knew it was wrong to ride on the car, that he knew McMahan was a policeman and that he had been warned to keep away from the cars.

The boy was beyond all doubt a wrong-doer and a trespasser at the time of the accident, and he took upon himself all risks and dangers arising from the act of riding on the car. Being a trespasser, McMahan, as the servant of the defendants, had a right to put him off. Though McMahan had this right, still he was in duty bound to use ordinary care in removing the boy from the car. Eor injuries to the boy arising from the want of such care the defendants are liable. 1 Shearman & Redfield on Negligence, [4 Ed.] sec. 89.

The question then is whether the evidence tends to show the want of such care. According to the evidence of McMahan he was in no way to blame, but there is much evidence to the contrary. That produced by the plaintiff is to the effect that McMahan pulled or jerked the boy off while the car was in motion, that McMahan was a cripple and therefore unable to handle the boy with care. It stands conceded that the boy had no notice or warning whatever. There is no doubt that the boy struggled when McMahan took hold of him, aud it may be but for his struggling he would not have been injured, but McMahan as a reasonably prudent man must have known that the boy would offer some resistance when grasped without warning. To take the boy from the moving car under the circumstances here disclosed was a dangerous undertaking, and the court did not err in submitting the issue of negligence to the jury.

*604It follows from what we have said that the fact that the boy was a trespasser will not, as a matter of law, defeat a recovery. There is certainly no other 'circumstance in evidence from which the court could, as a matter of law, declare the boy guilty of contributory negligence. The demurrer to the evidence was therefore properly overruled.

The evidence on the other issue discloses the following facts: Some three or four months before the accident the mayor of the city of Sedalia, at the request of some of the railroad officials, appointed McMahan a special policeman. The appointment was in writing signed by the mayor. McMahan had been appointed for a like purpose and in a like manner in the spring of every year for a period of eight or nine years. During all that time he was employed by the railroad company as a watchman until it passed into the hands of the receivers and then by them. He wore a policeman’s star, but he did not wear the uniform prescribed for regular police officers and did not report to any city officer. It seems he had made some arrests prior'to his last appointment. During the eight or nine years it was his duty to keep trespassers out of the yards, to prevent persons from interfering with the men while at work, to see that the shops were properly closed at night and to carry the shop mail. It was also his duty to drive boys out of the. yards and keep them off the cars.

The ordinance above mentioned provides that any minor under the age of eighteen years who shall, without authority to do so, climb upon, enter or hang to any car while in' motion, shall be deemed guilty of a misdemeanor; and by another ordinance it is provided that the police officers shall, without warrant, arrest any one found guilty of violating the city ordinances.

It is no uncommon thing'for corporations and *605individuals to employ duly appointed police officers to watch, their property, and if such an officer so employed make an arrest for disorderly-conduct, the presumption is that he acted in his official capacity as the agent of the state, and not as the agent of his employer. Being an officer whose duties are prescribed by law, it should be presumed, until the contrary is made to appear, that his employment contemplates only the exercise of such powers as the law confers upon him. 2 Wood’s Railway Law, 1212; Tolchester Beach Improvement Co. v. Steinmeier, 20 Atl. Rep. 188; Jardine v. Cornell, 14 Atl. Rep. 590. The presumption is, however, one of fact, and it may be shown that in making the arrest he acted under orders of his employer, in which event the employer would be liable for the unlawful acts of the officer. Under the' ordinance before mentioned McMahan as a. police officer had a right to arrest the boy on view for hanging to the car; and if the evidence tended to show that he committed the negligent act when making or attempting to make an arrest, it would follow from what has been said that the question whether he acted under the orders of defendant or their authorized agent would be one for the jury.

But there is no such evidence. His evidence as well as all the circumstances in the case show that he did not intend to arrest the boy. His only purpose was to take the boy off the car and to drive him out of the yards, a thing not within the line of his duties as a police officer, but a duty devolved upon him by the defendants. He was their paid servant, and as such charged with the performance of duties other than those pertaining to the office of a policeman. At the time of the accident he was engaged in enforcing the rules and regulations prescribed by the defendants. In attempting to remove the boy from the car he was *606not doing, or intending to do, any act devolved upon Mm as an officer of the law, and the fact that he had been appointed a special policeman has nothing what ever to do with this case.

With this conclusion it is not necessary to discuss the refused instructions relating to, this branch of the case; nor is it necessary to consider the question made by counsel for the plaintiff that McMahan was not a police officer because he gave no bond and his appointment by the mayor was not confirmed by the city council.

The defendants, on the cross-examination of the father of the plaintiff, offered to show by him that he had been notified that the boy was in the habit of climbing upon the cars, and to keep the boy away, and that he had told the boy to stay away from the yards, which evidence the court excluded. This is an action' by the boy, and not the father, and the negligent omission of the father to keep the boy away from the yards cannot be imputed to the boy. Winters v. Railroad, 99 Mo. 510.

The offer to show that the father told the boy to stay away might have some bearing on the defense of contributory negligence, so far as to-show that the boy knew it was dangerous 'to cling to the moving cars. We think the judgment should not be reversed because of the exclusion of this evidence, since the boy himself testified in plain and distinct terms that he knew it was wrong to ride on the cars, and that he had been driven away from the yards on a number of occasions. With this evidence of the boy before the jury, the defendants could not have been prejudiced by the exclusion of that of the father on the same point. The judgment is affirmed.
