Police were called to 100 Mass Mills Drive, at the Massachusetts Mills apartment complex, at 5:34 p.m., for a report of one, or possibly two men stabbed.
Officers quickly determined only one man was stabbed. A 22-year-old man who lives in the building suffered a stab wound to the shoulder, but did not appear to be seriously injured. He walked into an ambulance on his own power before he was driven to Lowell General Hospital.
He was later transferred to a Boston hospital, but police said his injuries were non life-threatening.
The 22-year-old told police he was stabbed by his 42-year-old roommate after a verbal argument turned physical.
The roommate, Noel Cintron, 42, was arrested at the scene and charged with domestic assault and battery with a dangerous weapon (knife). The charge is a domestic since the two men are roommates.
Cintron is being held tonight pending arraignment in the morning.
