Police are on the hunt for a man who stormed a pub in the Russian Hill neighborhood and assaulted four men with pool cues and balls, officials said Wednesday.

The man, described as between 30 and 40 years old, entered a business on the 1000 block of Columbus Avenue about 4:55 p.m. and began yelling and pelting customers with pool balls and cues, according to the San Francisco Police Department.

“It looks like the suspect literally just came into the business and there was no sharing of words, any kind of conversation,” said Officer Robert Rueca, a spokesman for the San Francisco Police Department. “This person just seemed to be on a rant and started his act of violence without any provocation.”

Four men — ages 25, 33, 48 and 51 — were taken to a hospital and treated for injuries police said were not life-threatening. All four victims were San Francisco residents, according to Rueca.

The suspect, who fled the scene on foot, has not been apprehended, police said.

“We’re still investigating the matter, and no suspects have been identified yet,” Rueca said.
