The owner of Suleyman’s Market in Cleveland, Ohio was tending to the store when a pair of masked and armed men came in and attempted to rob him. Outside the store, a man witnessed the robbery and flagged down a police car.
The owner complied with the robbers’ demands for cash, but as the pair attempted to flee the market they spotted a police officer waiting for them outside. The thieves retreated into the store, prompting the store owner’s friend to retrieve a gun and confronted the robbers. Eventually, the friend was able to detain the criminals, who were then taken into police custody. (Cleveland.com, Cleveland, Ohio, 03/31/16)
