CHICAGO – A Cook County judge ordered a Chicago man held after sheriff’s police say they found him with a pistol outfitted with a laser sight late last month.

What we know:

On Aug. 29, Cook County Sheriff’s Police Investigators were working near 93rd Street and Cottage Grove Avenue when a witness reported seeing a man brandishing what appeared to be an AR-style pistol in the 8700 block of South Dauphin Avenue on the South Side.

Police said they found a man who matched the description, identified as 18-year-old Larry Thompson of Chicago. Investigators said they recovered a backpack containing a pistol with a laser sight and a loaded magazine.

He was charged with aggravated unlawful possession of a weapon.

Thompson appeared in court on Aug. 30, when a judge ordered him detained at Cook County Jail.
