Downtown S.F. shooting - one wounded

(12-02) 17:35 PST SAN FRANCISCO -- A man was shot and wounded just off Market Street in downtown San Francisco on Monday afternoon after an argument turned violent, authorities said.

The victim, whose identity was not immediately released, was rushed to San Francisco General Hospital, said police Sgt. Danielle Newman.

He was conscious when emergency crews reached him. Newman said she did not know how many times he'd been shot or what condition he was in.

Police detained a man connected to the shooting, but he was not necessarily a suspect and there were no immediate arrests, Newman said. Witnesses reported seeing the gunman flee on a bus.

The shooting occurred at about 1:30 p.m. at Jones Street near Market after two men began arguing and one pulled out a gun, witnesses said.

Several witnesses reported hearing four to eight shots, then witnessing one of the men stagger toward Market, where he collapsed on the sidewalk about half a block from the site of the shooting.

The gunfire left at least one bullet hole in the wall of a check-cashing store, and a block of Jones Street was shut down while police investigated the crime.

Further details about what happened were not immediately available.
