Police arrested a man who allegedly tried bringing a loaded gun in a baby stroller into Six Flags Great America in Gurnee on Saturday, prosecutors said.

The Gurnee Police Department was notified after security reported a person with a gun at the theme park.

Lake County Assistant State’s Attorney Jason Humke said Clishaun Long, 28, of Peoria, had been pushing a stroller by himself.

Officers detained Long at the security checkpoint to the park.

An x-ray screening showed what appeared to be a gun in a bag, Humke said.

A .40 caliber handgun was recovered from a diaper bag. The gun had a loaded magazine and had a round in the chamber.

Long’s social security card was located next to the gun, Humke said.

Court records show Long does not have a Firearm Owner Identification card or concealed carry license.

Long is currently on parole in Louisana for a robbery conviction. A parole violation warrant has been issued following his arrest.

The Lake County State’s Attorney’s Office charged Long with felon in possession of a firearm and two counts of aggravated unlawful use of a weapon.

Lake County Judge Janelle Christensen ordered Long held on a $100,000 bond during an initial court hearing Sunday.

Long remains held in the Lake County Jail and would need to post $10,000 cash in order to be released.

A status of attorney hearing is scheduled for Wednesday.
