Two Bangor area women were arrested early Thursday after state drug agents and police seized a half-pound of heroin, the equivalent of 2,300 doses, valued at $60,000 during a traffic stop in Bangor.

Stephen McCausland, spokesman for the Maine Department of Public Safety, said the women had been recruited by a state prison inmate to conduct drug runs to New York City and sell the heroin in Bangor.

The drug trafficking operation was being coordinated by an inmate at the Maine Correctional Center in Windham. The prisoner was arrested in April 2015 by drug agents in Aroostook County after he was found with 50 grams of heroin. He was convicted of aggravated trafficking in heroin and is serving a five-year sentence.

In a press release, McCausland said the inmate allegedly “coordinated the drug importation from inside the Windham prison.” The Maine Drug Enforcement Agency is not naming the inmate because he has not yet been charged.

Arrested around 2 a.m. Thursday was 24-year-old Monique Nichols of Hudson and 53-year-old Wanda Wyman of Bangor.

Nichols and Wyman were each charged with trafficking in schedule W drugs. They are being held at the Penobscot County Jail.
