A man suffered wounds that were not life-threatening when he was shot early Sunday morning in the area between Harvard University and the Massachusetts Institute of Technology, Cambridge police said. The man, who is in his early 20s, was probably shot in the area of Harvard and Cherry streets about 4:30 a.m., police spokesman Dan Riviello said. Detectives found several spent shell casings at the scene. Riviello said the man, who is not a Cambridge resident, was treated at Boston Medical Center for gunshot wounds in an arm and a leg and was still in the hospital as of 6:30 p.m. Sunday. He said police are looking for a male suspect but could not immediately provide any other details. Police do not know if the suspect is known to the victim, Riviello said.
