CHICAGO (CBS) — Twenty-one men are now facing charges after a prostitution sting in northwest Cook County.

The men responded to online ads and showed up Thursday at a hotel.

They agreed to pay a person who turned out to be an undercover officer with the Cook County Sheriff’s Office.

All 21 men received $1,000 fines, and the Sheriff’s Office towed their cars.
