26-year-old Kevin E. Gillman of Whitehall, Ohio weighs almost 500 pounds.  And like everyone who weighs almost 500 pounds, when he goes to Walmart, he rides one of their motorized shopping scooters.

But on Tuesday, for whatever reason, Kevin decided to use that motorized scooter for some LOW-SPEED SHOPLIFTING.

First Kevin grabbed some paint.  Then he drove himself to the clothing section, threw some paint on the clothes, and SET THEM ON FIRE.  That fire was SUPPOSED to be a distraction while Kevin stole electronics.

But the fire created CHAOS . . . and the store's front door got locked, which blocked him from escaping.  Yes, Walmart's door got LOCKED during a fire, trapping everyone in.  But that's an issue for another day.

Kevin was arrested for aggravated arson and petty theft.

Here's Kevin's mugshot, plus surveillance photos of him on the scooter.
