Providence College officials are warning students about two gun-toting men who have been threatening people who refuse to give them cigarettes.
Police Maj. Thomas Verdi tells the Providence Journal his department is increasing patrols after several students reported they were approached by the men near campus on Tuesday night.
He says the suspects would ask for a cigarette, then pull a gun when their request was rebuffed.
Police says the suspects threw a glass bottle at two people who they had approached on Pembroke Avenue. Another man says he was punched in the face by one of the suspects. A third group said they heard gunfire after the men left.
Police have not made any arrests.
