Fort Wayne police are investigating a robbery last night at the KFC restaurant on South Calhoun at Pettit. They were alerted to what was going on when a passerby reported seeing three armed men inside. Witnesses confirmed that the men came in wearing dark clothing with their faces concealed and demanded cash. They later forced everyone into a walk-in cooler in the rear of the restaurant before they took off. Nobody was hurt, but police are asking anyone with who knows anything about this latest armed robbery to give them a call. You can also make an anonymous report through Crime Stoppers.
