San Francisco police have released video surveillance images of the suspect in a brutal stabbing in Cow Hollow earlier this month.
A 20-year-old man suffered severe lacerations on his arms during what police called a vicious and unprovoked attack near Union and Buchanan streets about 1 a.m. on Aug. 4.
Police have not released details on what led to the stabbing. The initial report of the incident stated a brawl escalated between the suspect and victim outside a bar in the 3000 block of Buchanan Street. At one point the suspect slashed at the victim with a knife, Officer Tracy Turner said.
The victim was transported to San Francisco General Hospital, where he underwent surgery to repair nerve damage caused by the attack, Turner said.
The victim is now recovering at home, she added, but the suspect remains at large.
Police hope the surveillance images released Wednesday will help investigators make an arrest.
The suspect is described as either a white or Hispanic man in his 20s. He is about 6 feet tall, weighs about 170 pounds and has a close buzz cut hairstyle. The night of the attack he was wearing a white T-shirt and blue jeans.
