The owner of Tacos El Mazatlan food truck in Oakland, Calif. was cleaning up the area around the truck when a pair of armed criminals approached and demanded money. At first the owner tried to flee, but one of the criminals fired at him, striking him in the back and leg. The owner then took cover, drew a gun and returned fire, wounding one criminal and causing both to retreat to a nearby getaway car. The pair, along with their getaway driver, was captured a short time later when the wounded robber sought medical attention.
 The owner of the truck began arming himself after a previous robbery attempt and keeps body armor in the truck as an added precaution.
