Man bites off bartender’s finger in SF’s Marina

A man who went berserk and bit off a bartender’s finger after getting booted from a karaoke bar in San Francisco’s Marina district at closing time remained on the loose as police sought the public’s help Monday in trying to identify and capture him.

San Francisco police officials released security video showing the shirtless suspect around the time of the attack in hopes someone who knows him comes forward. The Chronicle later obtained a 6-second cell-phone video posted on Snapchat that showed the man tussling with a buddy in front of the bar where the finger-biting incident occurred.

The July 17 attack happened outside the Silver Cloud Restaurant & Karaoke Bar at Lombard and Webster streets around 2 a.m., police said.

The man had been drinking at the bar that night and tried to go back inside after it closed, said Officer Carlos Manfredi, a San Francisco police spokesman. After being denied entry, the man tried to get in through a small window, but was again stopped by the bartender.

The patron then flew into a rage and started kicking and yanking the bar’s front door, Manfredi said.

The bartender went outside and told the man to knock it off. Rather than cooling down, the man attacked the bartender, punching him in the face and eventually biting his left ring finger off during the scuffle, police said.

The man then bolted with his buddies who had also been inside the bar.

The bartender ended up going to a hospital, where he was treated for cuts, scrapes and bruises on his head, swollen eyes and a severed finger. Doctors were unable to reattach the man’s ring finger, police said.

The suspect is described as 6 feet tall, weighing 180 pounds with black hair and brown eyes.

Video of the man shows him wearing a pink shirt, blue jeans and brown shoes around the time of the attack. In one of the videos, the man is seen tussling with a friend who was wearing a leather jacket.

Anyone who recognizes the suspect is asked to call San Francisco police at (415) 575-4444.
