WEST VALLEY CITY — Workers at a West Valley City Mexican food restaurant foiled an armed robbery with a few spritzes of oven cleaner.

Police say a gunman entered the kitchen at El Calor Taqueria about closing time Sunday night and demanded money. A struggle ensued, and one of the employees sprayed the cleaning chemical in the man's face. Authorities say he fell to the floor in pain and suffered chemical burns to his face and eyes.

Officials say at least three of the employees sat on top of the man until police could arrest him.

The man was booked in the Salt Lake County Jail.
