A masked gunman forced his way into a Joliet mall safe on Friday night, duct taped employees and then fled with cash.
The robber hid in the Louis Joliet Mall's Carson Pirie Scott as staff began locking up for the night, said Joliet Police Cmdr. Brian Benton, according to the Chicago Sun-Times.
Benton said he pointed a dark-colored handgun on a first employee who was unable to open the store's safe. The gunman led the employee downstairs where they encountered another employee who was able to open the safe at gunpoint.
The bandit, who was wearing a gray hooded sweatshirt and a bandana over his face, took the money and duct taped both employees.
On Monday, Benton said detectives were reviewing surveillance footage from the store.
