FARMINGTON — Police say a Farmington man is facing a class A felony charge of aggravated trafficking of an illegal drug after they found cocaine, pills, marijuana and other evidence of drug trafficking in his downtown residence.

Omer Havtan, 20, was arrested late Thursday night after police executed a search warrant of his apartment at 164 Broadway, Farmington police Chief Jack Peck said.

The apartment is within 1,000 feet of a drug-free zone — Meetinghouse Park, a public park owned by the town — which elevates the charge, he said.

The amount of cocaine and other substances found was not available Friday morning, he said.

Based on information received a few weeks ago about people dealing drugs in downtown Farmington, police began an investigation and applied for and received a search warrant, he said.

Officer Michael Lyman and Sgt. Edward Hastings IV led the search just before 11 p.m. Thursday.

Another person at the residence, Jonathan Toothaker, 22, was arrested on two warrants and on a charge of violation of conditions of release, Peck said.

On Friday, both remained at Franklin County Detention Center, where Havtan’s bail was set at $25,000 cash and Toothaker’s at $3,940, Peck said.
