Deangelo Cooper, 37, of Joliet.

Police say they arrested a convicted felon after the man allegedly pulled out a loaded defaced handgun and began threatening people at a party in Zion.

The Zion Police Department responded around 1 a.m. Sunday to the 2400 block of Joanna Avenue in Zion for a report of a person with a gun.

Zion Police Department Lt. Derek Zaloudek said a person attending a party produced a handgun and began threatening other attendees and residents.

Officers arrived and found the suspect, identified as Deangelo Cooper, 37, of Joliet, outside attempting to re-enter the residence.

Cooper attempted to flee to the rear of the residence but was almost immediately arrested, Zaloudek said.

Officers recovered a loaded Walther Creed 9mm handgun from Cooper’s possession.

The gun had a defaced serial number. Zaloudek said Cooper was also found with two cigar package wrappers filled with additional 9mm ammunition.

Cooper is a convicted felon and is not legally permitted to be in possession of firearms, Zaloudek said.

The Lake County State’s Attorney’s Office approved numerous charges against Cooper, including armed habitual criminal, unlawful use of a weapon by a felon and possession of a defaced firearm.

Cooper was transported to First Appearance Court on Monday and he was remanded to the custody of the Lake County Jail.

The state’s attorney’s office filed a petition to detain him pending trial. The petition was granted by a judge.

A preliminary hearing is scheduled for April 11.
