A Massachusetts man has been arrested and a large quantity of heroin and cocaine seized following a months-long investigation into a drug dealing operation in northern Maine.

Drug agents arrested 38-year-old Don Twiggs of Hyde Park, Massachusetts on Monday and charged him with Class A aggravated trafficking in Schedule W drugs.

Maine Drug Enforcement agents seized 250 grams of heroin and cocaine that Twiggs intended to sell in Penobscot and Piscataquis counties, Steve McCausland, spokesman for the Maine Department of Public Safety, said in a release Wednesday.

Twiggs was being held Wednesday on $15,000 cash bail at the Penobscot County Jail.

Drug agents allege that Twiggs would make regular trips to Massachusetts, where he would purchase drugs. He would then transport “significant amounts of heroin back to Maine for redistribution in the two counties.”

The investigation, which involved the undercover purchase of heroin, culminated Monday night when drug agents and state troopers stopped Twiggs’ vehicle at the Newport exit off Interstate 95. A search of his vehicle led to the seizure of drugs with a street value of about $55,000. The 200 grams of heroin represents about 2,000 individual doses.

Drug agents also searched a home on New Jersey Street in Millinockett where Twiggs had been living. Additional evidence of drug trafficking was found inside the home.

The investigation is continuing and more arrests are possible.
