Vallejo police say that a masked gunman robbed the McDonald's restaurant on Lincoln Road East at about 3 a.m., taking money from the cash registers.

The McDonald's night manager told responding police officers that a male pointed a gun at him and ordered him and a female employee to go to the back of the restaurant and strip, Lt. Kenny Park said. The suspect then locked them in a room, stole money and fled before police arrived.

He was described as a black male wearing a black ski mask. There were no injuries.
