A 4-year-old Ottawa boy was shot in the face with a BB gun Sunday afternoon when it went off while he and another 4-year-old boy were playing with it, Ottawa Police Department officials said.

Ottawa police responded to the incident about 3:15 p.m. Sunday at a residence in the 500 block of East Fifth Street, where they found a child had been shot in the cheek.

“The BB gun was stored in the closet of a room that was normally locked, but an older sibling was in the room at the time,” Capt. Adam Weingartner, with the Ottawa Police Department, said.

The child did not sustain a serious injury from what police have labeled as an accidental shooting.

“The boy did not require medical attention, but the [BB] left a bruise on his cheek,” Weingartner said.

Weingartner said no criminal charges would be filed in the case.
