A Madison man turned himself in to police Tuesday after he allegedly attacked a woman at the Willy Street Pub and Grill early Sunday.
The victim suffered a concussion and separated shoulder in the incident, police said.
Eric Prunn, 38, was allegedly flirting with a 23-year-old woman prior to the incident, according to the police report.
The victim told police the suspect stuck his hand down her shirt and groped her. The victim then stopped the suspect and put her hands on his chest to keep him away, Madison Police Department spokesperson Joel DeSpain said.
""She said she was pushed so hard that she came out of her shoes and reports other patrons intervened to stop the attack,"" DeSpain said in a statement.
The victim went outside to call 911 and the suspect allegedly threw a beer bottle which struck the back of her head.
