Three City of Dunkirk residents and a Fredonia man were arrested on multiple drug charges Wednesday following a police raid on a Dunkirk residence, according to the Chautauqua County Sheriff's Office.
Dunkirk City Police and members of the Southern Tier Regional Drug Task Force executed a search warrant at about 8:37 a.m. at a Roberts Road residence in the city, where they seized more than a half-ounce of heroin, marijuana and a sum of money, the Sheriff's Office said.
Authorities said the search warrant was issued based on a monthlong investigation.
During the investigation, agents from the task force made controlled purchases of heroin from those arrested, the Sheriff's Office said.
Police arrested Onix Lopez-Ortiz, 38, Jann Montanez-Calderon, 38, and Myra Rivera-Cruz, 28, all of Dunkirk, and Pedro L. Rivera, 59, of Fredonia, the Sheriff's Office said.
All four were charged with two counts each of third-degree criminal possession of a controlled substance, authorities said.
Lopez-Ortiz was also charged with third-degree criminal sale of a controlled substance and seventh-degree criminal possession of a controlled substance when he was found to be possession of an additional quantity of heroin while being booked in Dunkirk City Jail, the Sheriff's Office said.
All of those arrested were held in Dunkirk jail, without bail, pending arraignment and court action, the Sheriff's Office said.
The Southern Tier Regional Drug Task Force is comprised of investigators from the City of Dunkirk Police and Chautauqua County Sheriff’s Office.
