Three gamblers were robbed of money early Friday at Rivers Casino in Des Plaines.
About 4:30 a.m., security at the casino reported that a thief working inside the casino, at 3000 River Road, cashed out credits after each of the gamblers left slot machines temporarily unattended, Des Plaines police said.
The thief stole $150 from one machine, police said. The amount from the others wasn’t known.
Security video showed the thief was a man wearing a black winter coat, according to police.
