ALAMEDA -- An employee of Papa Murphy's Take 'N' Bake Pizza suffered a broken cheek bone when a robber pistol-whipped him Tuesday night when he could not unlock the business safe, police said.
The robber also punched another employee before he fled with an undisclosed amount of cash.
Five employees were in the restaurant at 1929 Broadway when the suspect entered about 8 p.m. and ordered them to lay face down on the floor, police Lt. Ted Horlbeck said.
The robber, who was armed with a semi-automatic handgun, stole money from the register and from one employee, police said. He also stole wallets from two of the workers.
Along with a broken cheek bone, the 20-year-old employee who was pistol-whipped suffered a laceration on his left ear that required eight sutures to close, police said. He was treated at Alameda Hospital and released.
The other employees inside the restaurant were two men, who are both age 22, and two 17-year-old girls.
The suspect was last seen running away from the business -- which is near the Fruitvale Bridge and the Bridgeside Shopping Center -- southbound on Broadway, Horlbeck said.
The employees said the man, who was black, was wearing all dark clothing, gloves, a hoodie and either a ski mask or a scarf wrapped around the lower part of his face. He has a deep voice and stands between 6 feet and 6 feet 4 inches tall and weighs between 180 and 250 pounds.
The man is also believed to between 27 and 33 years old.
Alameda police ask anyone with information on the robbery to call 510-337-8340.
