ATLANTIC CITY- Police released a photo today for a suspect in an armed robbery Sunday on the boardwalk.

Police responded at the Johnny Rockets restaurant at Bally's at 3:55 a.m. where the restaurant manager said she had been robbed by a masked man. 

The man knocked on the rear door of the restaurant claiming he was "Bally's security," police said. The manager said he held a handgun against her forehead and ordered her to open the safe and transfer the money into deposit bags, which he put into a backpack.

The manager's hands and feet were tied, while the suspect fled on a bike heading north toward Pacific Avenue, police said. She was eventually able to free herself and call police.

The man is described as tall, about 5 feet 8 inches, with a medium build, wearing khaki pants, black gloves, a black baggy coat and black slip-resistant shoes.

Police are also searching for an accomplice, who may have brought the bicycle.
