A 21-year-old man was shot and wounded by a driver who rear-ended his car as they exited the Bay Bridge in San Francisco, police said Thursday.

The gunfire broke out about 10 p.m. Wednesday when both drivers pulled over at Fremont and Folsom streets and got out of their vehicles to inspect the damage, police said.

After he was shot, the victim was driven to a hospital by a relative, police said. The gunshot wound was somewhere in his lower torso, said Officer Carlos Manfredi, a police spokesman.

The police report didn’t list “any rhyme or reason” for the shooting, Manfredi said.

The man who crashed into the victim’s car and shot him has yet to be arrested or identified.

Further information wasn’t immediately available.
