A bicyclist was wounded when someone shot him without any warning while he was riding along the Los Angeles River in Long Beach on the Fourth of July, according to police.

The man and a woman were riding their bicycles on the riverside path near Del Amo Boulevard around 6 p.m. when a bullet hit the man in the lower body, Long Beach police spokeswoman Nancy Pratt said.

“The victim did not know where the shot had come from,” Pratt said.

Authorities took the man to a hospital to treat the wound, which didn’t appear to be life-threatening, Pratt said.

Police are still trying to find out who is responsible for the shooting. They asked anyone with information to call detectives at 562-570-7370.
