Man stabbed in Porter Square; suspect rides off on a bicycle

Cambridge Police report they are looking for Stephen Picard, 45, on charges he ended an argument by plunging a knife into another man's arm around 10:30 p.m. in Porter Square yesterday.

Picard and a pal then got on bicycles and pedaled north on Mass. Ave.

Police say they found the victim, a Somerville resident, standing on White Street, bleeding from his arm. He was taken to a local hospital for treatment of non-life threatening injuries.

Picard, who is, as they say, known to police, is described as white and heavy-set and wearing glasses and an orange shirt. He's often seen riding a mountain bicycle and has no known address.

If you spot him, police say don't approach him - he has a knife, after all - but instead call 911 or 617-349-3300.
