TULSA, Oklahoma - A man washing his food service truck was robbed at gunpoint Monday morning near 21st and Garnett. Police say the armed robbery victim was at the Clearwater Car Wash when he was approached by two men, one carrying a handgun.

The gunmen also hit the robbery victim on the head, knocking him out, according to an officer at the scene. They took his cell phone, wallet and cash.

The man went next door to the Casa De Marcos restaurant to call police.

He didn't get a good description of the men but told police they left westbound from the car wash.
