Stings conducted by the Cook County Sheriff's Department and several suburban Chicago police forces led to the arrest of 73 potential sex buyers.
Authorities say among those arrested was a man charged with child endangerment for having his 5-year-old child in the back seat of his vehicle while he solicited an undercover officer.
The Lake County Sheriff's Gang Task Force also conducted a sting, resulting in the arrest of eight men, all charged with solicitation of a sex act.
The efforts were part of a nationwide crackdown on sex-trafficking that resulted in the arrest of at least 473 sex buyers by law enforcement agencies across 12 states.
