BIDDEFORD, Maine — The Maine Drug Enforcement Agency arrested three men this week during what it’s calling one of the largest crack cocaine seizures ever in the state.

Police seized two points of crack, a “substantial amount” of heroin, six handguns, and $27,000 in cash, Maine Department of Public Safety spokesman Stephen McCausland said in a Thursday night news release. The drugs carry an estimated street value of $125,000.

Eric Adams, 38, of Waterbury, Connecticut; Obrian Barrett, 29, and Todd Milliken, 35, both of Biddeford, are being held at York County Jail in Alfred and face charges of aggravated trafficking in schedule drugs, a Class A crime.

Police expect more arrests will be coming.

The MDEA and FBI Southern Maine Gang Task Force have been investigating a large-scale heroin and crack cocaine distribution network in the Biddeford-Saco area for the past year, according to McCausland. Investigators say Adams brought heroin and crack from out of state to Barrett, Milliken and others, which was sold in the area.

Undercover agents purchased heroin and crack from all three men, McCausland said.

Police arrested Adams and Milliken on Wednesday at a room in the Hampton Inn in Saco. Barrett had rented that room. Milliken had a loaded handgun, crack and heroin on him. Agents swept the room and found about 520 doses worth of crack cocaine, 400 doses of heroin, and the cash.

Barrett was arrested by Biddeford police on Thursday after officers stopped a vehicle in which he was a passenger.

Bail for each man was set at $150,000 cash.

After the arrests, agents searched a storage unit at Atlantic Mini Storage in Arundel, where the suspects allegedly stored a large amount of drugs. There, agents found more crack, heroin, and five handguns, according to McCausland.

“The arrests and seizures is another example of out of state drug distributors transporting large amounts of drugs into Maine and selling them through local dealers,” McCausland said. “In addition, the handguns seized were likely to be distributed to criminal elements in other states.”
