The Maine Drug Enforcement Agency searched a house in South Thomaston for a suspected methamphetamine lab Feb. 26.

The resident of the home, Paul Mahonen, 36, was at the property when agents arrived. He was arrested and charged with trafficking in methamphetamine and is being held at the Knox County Jail on $5,000 cash bail.

Agents armed with a search warrant arrived at the house, located at 542 St. George Road (Route 131), in the late morning, according to a news release from the Maine Department of Public Safety.

Assisting agents were representatives from federal, state and local agencies.

Agents and a team chemist wearing protective suits searched inside the house and collected evidence of methamphetamine production, including chemicals and plastic bottles, according to the release. The lab team finished their work at about 2:30 p.m.

James Pease, a supervisor with Maine Drug Enforcement Agency, was the lead contact on the scene.

"It has gone very smoothly," he said. "Due to the nature of the process and its potential dangers" the South Thomaston Fire Department and Ambulance Service were on the scene as well.

On Feb. 19, multiple law enforcement agencies arrested a man at the same South Thomaston home and seized drugs believed to be bath salts.

Maine Drug Enforcement Agency agents, state troopers and Knox County Sheriff’s deputies arrested Leonard D. Wells Jr., 53, of Greenbush on judicial arrest warrants from Penobscot County for burglary and violation of conditions of release.

Agents found Wells hiding out at the South Thomaston home during a routine probation check at the residence.

Once arrested, agents seized about 20 grams of what is believed to be bath salts from him. Wells was arrested and charged with possession of synthetic hallucinogenic drugs. Wells was arrested on felony drug charges in Penobscot County Jan. 18 and posted bail.

Agents were assisted at the scene by the Maine Department of Environmental Protection, The U.S. Drug Enforcement Agency, South Thomaston Fire and EMS, State Police and the Knox County Sheriff’s Office.

The investigation will continue and additional arrests are possible.
