An Edinburg man who was on probation following the discovery of a meth lab at his home was charged again with the same crime on Tuesday, police said.

The Maine Drug Enforcement Agency, assisting probation officers last week in a search of Eugene Pomeroy's home on Edinburg Road, discovered evidence of a meth-making operation, Stephen McCausland, spokesman for the Maine Department of Public Safety, said in a Wednesday news release.

Pomeroy, 49, was initially charged on May 4 with a probation violation, but drug agents upgraded that charge Tuesday to aggravated unlawful operation of meth lab.

He was already on probation in connection with the August 2016 discovery of a suspected meth lab at the same home on Edinburg Road.

Pomeroy was transported to the Penobscot County Jail.
