Authorities in southeastern Michigan are investigating a Newport pizza shop robbery by two masked men.
Monroe County sheriff's officials say the men ordered three employees at Mary Sacco's Pizza to the floor Sunday night while forcing a fourth worker to hand over cash register drawers.
One of the robbers was armed with a knife. Witnesses told police the men wore hooded sweat jackets and covered their faces with cloths.
They drove off after the holdup. No one was injured.
