What began as an East Hampton Town police drunken driving stop in Montauk on Saturday resulted in a charge that the driver intended to sell drugs. Mateusz Z. Pieta, 20, of Baiting Hollow was driving a 2002 Lexus on Carl Fisher Plaza, near Edgemere Street, when he passed an unmarked police car at about 1:15 a.m. He then crossed over the double yellow lines into oncoming traffic, according to police, who pulled him over. He appeared drunk, the report said. Police also noticed a large plastic bag with marijuana on the floor of the Lexus, next to his leg. During a search, police found a plastic bag of cocaine in his pants pocket. The officers then searched the Lexus. In all, police allegedly found more than one-eighth of an ounce of cocaine and nine plastic baggies, an electronic scale, boxes of Narcan, and $265 in cash, as well as a plastic bag containing a green leafy substance that later tested positive for more than 25 grams of marijuana.Mr. Pieta was charged with criminal possession of a controlled substance in the third degree, a felony, and criminal possession of a narcotic in the fourth degree, also a felony, as well as driving while intoxicated and criminal possession of marijuana, both misdemeanors.Police also said they found a smoking device cartridge with a brown substance that later tested positive for the presence of marijuana. That resulted in a charge of criminal possession of a controlled substance in the seventh degree, a misdemeanor. East Hampton Town Justice Lisa R. Rana set bail at $25,000 cash or $50,000 bond.
