San Diego police say a boy throwing rocks at vehicles was struck in the abdomen by a crossbow bolt fired by a passenger in small sport utility vehicle.

Officer Dino Delimitros says the boy and a friend were throwing rocks in the Linda Vista neighborhood Monday afternoon when a passenger in a black Toyota RAV4 pulled out a crossbow and fired.

The boy was shot in the abdomen and was taken to a hospital. The San Diego Union-Tribune newspaper says his injuries are not life-threatening.

His name and age weren't released.

Nobody has been arrested.
