Windsor police are investigating after a man attempted to steal the purse of a 70-year-old woman waiting at a bus stop on Ouellette Avenue.

Investigators say a suspect armed with a knife robbed the woman in the area of Ouellette and Wyandotte Street on Monday, striking her in the face in the process.

A witness then reportedly pushed the suspect into a wall, forcing him to drop the purse.

The woman was transported to hospital for treatment of non-life-threatening injuries after suffering a cut to her nose.

The suspect is described as a white male in his 30s, about 250 pounds with a chubby face and short, blonde-ish hair. He was wearing a black t-shirt and grey cargo shorts.

Anyone with information is asked to contact police at 519-255-6700 Ext. 4830 or Crime Stoppers at 519-258-8477.
