Ypsilanti police are working to identify a man they said shoved a woman to the ground during an attempted robbery Wednesday afternoon.

The 44-year-old Ypsilanti Township woman was walking in an alley east of South Prospect Street between Davis Street and Maus Avenue at 4 p.m. when a man grabbed her from behind, police said.

He demanded money, but police said the woman refused to let go of her purse and started yelling. At one point, she was shoved to the ground. Det. Sgt. Troy Fulton said the man left the area without taking anything. The woman suffered some scrapes, Fulton said.

The victim wasn't fluent in English and had to contact a friend to help relay information to police. Police took a report on the incident 45 minutes after it happened, Fulton said.

The suspect was described as black, in his mid-30s and tall. He was wearing a black stocking cap, black sweater and black pants, police said.

Anyone with information can call police at (734) 483-9510.
