Police were called to a disturbance in the 700 block of Park Avenue a little after 1:00 o’clock Tuesday morning. Officers say when they arrived two groups of people were dispersing and witnesses told them nothing serious happened. About half-an-hour later police got a report from the hospital of a 19-year-old man turning up with a stab wound to his abdomen. He was held overnight for observation. Officers think they have an idea of the suspect’s identity.
