According to investigators, 21-year-old Jonathan Hewson  was dressed in a fully masked Spider-Man costume and walked into the Atwood Express in Pittsburgh's Oakland neighborhood and yelled “How much money you got?”

The clerk told police that he felt threatened and pulled out a stun gun and attempted to shock Hewson. Investigators said Hewson was scared off and ran away – only to be arrested a block away less than hour later.

News crews were there as Hewson was taken to the Allegheny County Jail in handcuffs.

Hewson’s roommate said his friend dressed up like Spider-Man often and doesn’t think his friend was trying to rob the store.

“He was hanging out with a bunch of friends, running around in a Spider-Man costumer. It’s just a misunderstanding of somebody robbing a store. I don’t think that would actually happen,” Chris Esposito said. “He’s a Spider-Man enthusiast. He’s a college kid and college kids do strange things.”

Investigators said there is surveillance video of the incident.

Hewson was arraigned on robbery charges late Friday morning. A judge set his bail at $50,000 bond and was ordered to have a mental evaluation.
