A six-hour standoff with an armed man inside a Lewiston hotel has ended peacefully. Police arrested Jeff Sewell at about 1 a.m. Wednesday and charged him with criminal threatening with a dangerous weapon and causing a police standoff. Police responded to the Morning Star Inn at about 7 p.m. Tuesday following a dispute between Sewell and another man. That other man, Richard Lamothe, said he notified motel management when Sewell loaded a gun. Lamothe said Sewell appeared intoxicated. City officers as well as state police surrounded and evacuated the motel and closed the road to traffic as Sewell barricaded himself inside a room. Sewell eventually gave himself up and was taken to the Androscoggin County Jail.
