LEWISTON — Police and drug agents raided a home on Howe Street on Thursday, arresting seven and seizing what they said is evidence of heroin and cocaine dealing.

The apartment house at 63-65 Howe St., police said, has been the scene of three heroin overdoses since the middle of summer.

The Maine Drug Enforcement Agency, working with Lewiston police as part of Operation Hot Spots, had been watching the building for several months, according to MDEA Supervisor Matthew J. Cashman.

At about 7:30 p.m., agents with warrants went to the home to search for evidence of drug trafficking. They arrested five people who were inside at the time and another two who showed up while the apartment was being searched.

The following people were arrested:

* Tyron Calhoun, 24, of Lewiston, on two counts of unlawful trafficking of scheduled drugs and one count of trafficking in prison contraband. Police said Calhoun entered the jail with crack cocaine hidden on his body.

* Everton Jones, 18, of New York City, on a charge of unlawful trafficking in scheduled drugs.

* Keosha Pontoo, 23, of Lewiston, on charges of unlawful possession of a scheduled drug, violating conditions of release and on a warrant.

* Bryan Brennick, 23, of Lewiston, on a charge of unlawful possession of a scheduled drug. 

* Joanne Barry, 35, of Lewiston, on a charge of unlawful possession of scheduled drugs.

* Stephanie Webster, 31, of Lewiston, on a probation hold.

* James Robertson, 24, of Auburn, on three outstanding warrants.

As they searched the home, police said they recovered 33 pre-packaged units of heroin intended for distribution, 21 bags of crack cocaine, drug paraphernalia consistent with trafficking and approximately $2,000 in suspected proceeds.

Each of the suspects were taken to the Androscoggin County Jail in Auburn where they remained on Friday.
