SUMMARY ORDER

Plaintiff-appellant Ernesto Abreu sued various officers of the New York City Police Department pursuant to 42 U.S.C. § 1983, claiming that they violated his Fourth Amendment rights when they entered and searched his apartment on February 26, 2008, discovered over two ounces of marijuana, and arrested him. Abreu also sued for false arrest, malicious prosecution, and abuse of process. He now appeals from the November 10, 2010 judgment of the United States District Court for the Southern District of New York granting the defendants’ motion for summary judgment on all of these claims. Because the defendants did not violate Abreu’s constitutional rights when they searched his home, arrested him, and prosecuted him for possession of marijuana, we affirm the judgment of the District Court.

We review an award of summary judgment de novo. Gorzynski v. JetBlue Airways Corp., 596 F.3d 93, 101 (2d Cir. 2010). “Summary judgment is appropriate when, construing the evidence in the light most favorable to the non-moving party, ‘there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.’ ” Rojas v. Roman Catholic Diocese of Rochester, 660 F.3d 98, 104 (2d Cir. 2011) (quoting Fed. R.Civ.P. 56(a)). We assume the parties’ familiarity with the underlying facts and record of prior proceedings, which we reference only as necessary to explain our decision to affirm.

1. Illegal Search and Seizure

The officers who searched Abreu’s apartment on the night in question did so pursuant to a valid warrant, which was issued on the strength of defendant Detective Romero’s affidavit asserting that he had overseen a “controlled buy” of narcotics at the apartment. Abreu argues that the “controlled buy” did not occur as Detective Romero represented it, and accordingly that the search warrant was not supported by probable cause. However, “a search or seizure pursuant to a warrant is presumed valid,” and a party seeking to “challenge the truthfulness of factual statements made in the affidavit ... must show that there were intentional and material *26 misrepresentations or omissions in [the] warrant affidavit.” United States v. Awadallah, 349 F.3d 42, 64 (2d Cir. 2003) (citation omitted) (citing Franks v. Delaware, 438 U.S. 154, 164-72, 98 S.Ct. 2674, 57 L.Ed.2d 667 (1978)). Because Abreu adduced no evidence that the affidavit supporting the search warrant in this case contained intentional, material misrepresentations, the District Court correctly granted summary judgment to the defendants on this claim.

2. False Arrest and Malicious Prosecution

The District Court also correctly dismissed Abreu’s claims for false arrest and malicious prosecution. “Under New York law, the existence of probable cause is an absolute defense to a false arrest claim,” Jaegly v. Couch, 439 F.3d 149, 152 (2d Cir. 2006), and to a malicious prosecution claim, Savino v. City of New York, 331 F.3d 63, 72 (2d Cir. 2003). “An officer has probable cause to arrest when he or she has ‘knowledge or reasonably trustworthy information of facts and circumstances that are sufficient to warrant a person of reasonable caution in the belief that the person to be arrested has committed or is committing a crime.’ ” Jaegly, 439 F.3d at 152 (quoting Weyant v. Okst, 101 F.3d 845, 852 (2d Cir. 1996)). Like the District Court, we conclude that the defendants had probable cause to arrest Abreu after they discovered over two ounces of marijuana in his bedroom. Accordingly, the District Court correctly granted summary judgment to the defendants on Abreu’s claims for false arrest and malicious prosecution.

3. Abuse of Process

Finally, we conclude that the District Court correctly granted summary judgment on Abreu’s claim for malicious abuse of process. To make out such a claim, Abreu was required to demonstrate that the defendants employed legal process “in order to obtain a collateral objective that is outside the legitimate ends of the process,” such as retribution. Cook v. Sheldon, 41 F.3d 73, 80 (2d Cir. 1994). Abreu has proffered no evidence to suggest that the defendants had a collateral objective when they arrested and prosecuted him for possession of marijuana.

We have considered Abreu’s remaining arguments on appeal and conclude that they are without merit. Accordingly, the judgment of the District Court is AFFIRMED.
