A Plainfield South High School student was arrested after he was caught with a firearm, ecstasy and marijuana, police said.

About 12:10 p.m. Friday, a detective assigned as a school liaison at Plainfield South High School was notified of a photograph depicting firearms on the Instagram account of a 17-year-old male, Joliet police Sgt. Dwayne English said.

“Upon further investigation, it was determined that one of the firearms was at the juvenile’s residence,” English said.

A firearm with ammunition, as well as ecstasy pills and marijuana, were recovered by detectives at the juvenile’s residence, English said.
