¶1Defendant appeals his conviction for possession of a controlled substance. ORS 475.992. He claims that the trial court erred in denying his motion to suppress. We affirm.
¶2The trial court found these facts, which are supported by evidence in the record. The Malheur County Narcotics Task Force was conducting surveillance of defendant. It knew that he was a heroin addict and that his driving privileges had been suspended. On January 12, 1988, Deputy Sheriff Brunner, a member of the task force, saw defendant driving. On January 22, 1988, an officer in the task force saw defendant affix license plates to a vehicle at the residence of Sofia Alexander.
¶3As defendant walked down the street, Brunner and Kee arrested him for driving while suspended, based on Brunner’s January 12 observation. Officers Cummings and Hartley arrived at the scene. During a pat-down search, Cummings discovered two syringes. A second, more thorough, search was then conducted, which revealed heroin in defendant’s possession.
¶4Defendant concedes that the police could pat him down incident to his arrest for driving while suspended. He argues, however, that there was no justification for the second, more thorough search that revealed the heroin. We disagree.
¶5When the police conducted the second search, they *328had probable cause to arrest defendant for possession of heroin and to search for heroin incident to that arrest. The officers had seen a known heroin addict place license plates on a car to which the plates did not belong, enter a house for five minutes, and then go directly to a motel parking lot, where a lighter was repeatedly used in the car in a manner consistent with the heating of heroin. A short time later, they discovered two syringes on defendant. At that point, the officers had probable cause to arrest him for possession of heroin and, therefore, to search him for evidence of that crime. State v. Owens, 302 Or 196, 200, 729 P2d 524 (1986); State v. Weiland, 72 Or App 25, 28, 695 P2d 85, rev den 299 Or 32 (1985).
¶6Affirmed.
¶7 Although the trial court made no finding on the matter, Alexander apparently lived in Ontario.
¶8 At the suppression hearing, Brunner testified that heroin is heated before being used.
