Authorities recovered a loaded .38-caliber Smith & Wesson handgun from the bag, police claim.

He told authorities he carried the weapon for protection, police said.

Collier, of Flossmoor, is charged with unlawful possession of a firearm, unlawful possession of a firearm in a prohibited area, and not having a valid FOID card, the statement said.

He was processed and released on his own recognizance, the statement said.
