A man who was injured in a triple shooting at a nightclub in San Francisco's South of Market neighborhood early this morning is in critical condition but is expected to survive, a police officer said.
The victim, a man in his 30s, was shot around 1:30 a.m. along with two men in their 20s at the 330 Ritch nightclub on Ritch Street, a small alleyway off of Brannan Street, police said.
The other two victims were treated for injuries that are not believed to be life-threatening, while the victim in his 30s remains hospitalized in "critical but stable condition," Officer Carlos Manfredi said.
The officer said an argument prompted the first round of gunfire inside the club.
More shots were fired just outside of the club and in a public parking lot on Ritch and Brannan streets, Manfredi said.
He said investigators do not know what caused the fight.
"It's one of those incidents that happened really fast...and now we have three victims that are hurt," the officer said.
The suspects fled the scene before officers arrived and have not been located. No suspect description was available as of this afternoon.
Police are reviewing surveillance footage from the club to see whether the cameras may have captured the shooting, Manfredi said.
Anyone with information about the crime is asked to call the San Francisco Police Department's anonymous tip line at (415) 575-4444.
