A Detroit toddler shot himself in the head early Thursday morning when someone left a gun on his bed.

The boy was rushed to Children’s Hospital with what was believed to be a graze wound, WXYZ said, while police were looking for a 16-year-old sibling who abruptly left the house after the gunshot.

Detroit police said the incident happed at about 3 a.m. after the 3-year-old woke his father because he couldn’t sleep. The dad put him back to bed.

A short time later, the boy’s parents, both in the living room, heard the gunshot. The 16-year-old apologized to his father and ran from the house, WJBK reported.

Police are searching for the teen, who is reportedly on probation, and the gun, the station said.

The toddler is reported to be in stable condition. The father is cooperating with the investigation, and the boy’s mother is with him at the hospital.
