Joliet police are investigating after a 17-year-old boy was struck by a bullet while sleeping in his bed early Friday morning.

Police said they were called to the 900 block of Midland Avenue just after 3 a.m. for a report of shots fired. When they got there, they found a 17-year-old boy shot in the mouth while he was asleep in the bedroom of a nearby home.

Police said the gunshots came into the boy's bedroom from outside, hitting him while he was in bed. It was not immediately clear if he was struck by a stray bullet or if someone had been aiming at the home.

The teen was taken to St. Joseph Medical Center with non-life threatening injuries. Police found multiple shell casings in outside during their initial investigation.

A man and a girl also in the home at the time of the shooting were not hurt, police said.
