Tulsa Police said two Applebee's employees and a friend were robbed in the restaurant's parking lot early Monday.
Officer Leland Ashley said the trio were getting into their cars after closing the restaurant at 12:30 a.m. He said a light skinned black male wearing blue jeans, a gray hooded sweatshirt and a bandana covering his face approached with a gun and demanded money.
After getting cash and a cell phone, Ashley said the man ran away.
Police officers arrived and a search with assistance from a K9 officer failed to locate the man near the Applebee's restaurant in the 11100 block of East 41st Street.
None of the three victims were injured.
