Authorities said no one at the bar was shot.

Ravi Sharma was eating dinner when he heard gunshots at the bar.

“It was like, ‘Bam! Bam! Bam! Bam!’ I just saw people running. I heard gunshots and then we kind of like ran into the kitchen,” explained Sharma.

According to Michael Bowens, a bartender at Polo Grounds, the suspect was thrown out of the bar for after getting into a fight over a woman. He then came back in with a gun and fired 4 or 5 shots, at least one of them was at eye level.

“I saw the altercation when he got asked to leave, he got kicked out, and then he came back” said Bowens. “The door guy had the door held closed, saw the gun, let the handle go. Then the guy came in and popped off the rounds and then left. There was one [shot] that went through the window that was my head level.”

Arriving officers got to the scene and chased the suspect about two blocks. The suspect crashed his car into another vehicle at Townsend and Third Streets.

Video shot by KPIX cameras showed two vehicles — a dark grey sedan and a red SUV — that had been in a collision.

Hamid Sharfi told KPIX the suspect crashed into his car.

The suspect suspect then veered into a pole. He was injured, but still managed to run away. Police officers chased him on foot and caught up with him at Fifth Street and Bluxome.
