Two children were injured after an apparent accidental shooting outside a Chuck E. Cheese's restaurant Friday evening in southwest Fort Worth, police say.

Fort Worth police responded at about 6 p.m. to the restaurant off Southwest Loop 820 near the Hulen Mall.

Two 3-year-old children were exiting a vehicle when one of the children found a gun inside the vehicle and shot himself in the hand, according to police. The bullet also struck the other child in the side.

Both children were transported by a private vehicle to Cook Children's Medical Center.
