SAN DIEGO -- A 19-year-old man was grazed by a bullet in Mountain View in what may have been a gang-related shooting, police said Tuesday.

The shooting happened in the 3500 block of Webster Avenue. It occurred about 8 p.m. Monday night after a fight over a "road rage incident," San Diego police Lt. Margret Schaufelberger said.

The gunman fired six or seven shots and fled in a red Toyota Corolla, Schaufelberger said.

The victim, whose name police withheld, suffered a graze wound to an arm, but was not hospitalized, Schaufelberger said.

Both men knew each other and had violent contacts in the past over gang recruitment, Schaufelberger said. No immediate arrests were made.
