(ABC News) -- A University of Pittsburgh college student is facing a robbery charge after he allegedly tried to hold up a convenience store dressed as Spider-Man, authorities said.
Police arrested Jonathan Hewson, 21, early Friday morning after he allegedly walked into a convenience store and yelled at the clerk, "How much money you got?" ABC Pittsburgh affiliate WTAE-TV reported.
But when the clerk pulled out a Taser, Hewson's spidey senses began to tingle and he fled.
Police found Hewson about 30 minutes after the incident occurred, just a block from the store, and still dressed in full costume, WTAE-TV reported. Authorities said he did not have a weapon on him.
Hewson's roommate, Chris Esposito, said he believed his friend's bizarre behavior was a harmless prank gone awry.
"I think it's just a big misinterpretation, and everything that's being said of him has been misinterpreted," Esposito told WTAE-TV.
"He's a 'Spider-Man' enthusiast. He's just a college kid, and college kids tend to do strange things," he said. "He's not doing anything malicious or with bad intent."
Hewson was in custody today at Allegheny County Jail, a jail spokeswoman told ABCNews.com.
Pittsburgh Municipal Court Judge James Motznik arraigned Hewson on a robbery charge, set his bail at $50,000 and ordered the college student to undergo a mental evaluation, the Pittsburgh Tribune-Review reported.
Hewson's family did not immediately return ABC News' phone calls.
The Pittsburgh Bureau of Police did not respond to ABC News' request for comment.
