A 16-year-old accidentally shot himself in the head Sunday night while handling a gun on the Northeast Side, the San Antonio Police Department said.

Officers responded just after 8 p.m. to the 6400 block of Indigo Forest, according to a preliminary police report. They learned a 16-year-old boy “accidentally struck himself in the upper body while manipulating a weapon.”

The teen suffered a gunshot wound to the head, a sergeant at the scene told KSAT-TV. Medics took him to the hospital in critical condition.

Police did not provide an update on his condition Monday morning and said the investigation remains active.
