LEWISTON — A Lewiston man was arrested Monday at a Lisbon Road motel where police found more than 350 grams of heroin and/or fentanyl, methamphetamine, a loaded 9mm gun and more than $2,000 in cash.

Local police and the Maine Drug Enforcement Agency arrested Marcel Seeley at the Lighthouse Inn, Lt. Derrick St. Laurent, public information officer for the Lewiston Police Department, said in a statement Tuesday. An investigation into suspected drug trafficking led police to him, St. Laurent said.

Police found more than 350 grams of heroin and/or fentanyl in the motel room, as well as methamphetamine, a loaded 9 mm gun, more than $2,000 in cash and numerous prescriptions. Items related to the packaging and processing of drugs were also found, St. Laurent said.
