Yesterday's Warped Tour stop at Maryland Heights' Verizon Wireless Amphitheater wasn't all sunburns, music and fun for one of the bands. Gym Class Heroes front man Travis McCoy was arrested after tussling with a fan who had been heckling him during his band's day-closing set.

According to an eyewitness fan report, an audience member called McCoy an "ignorant nigger" during the set.

McCoy retaliates by beating him with the mic. ouch.

listen to the video tho.
At 22 seconds in, McCoy says: "Listen, that's not even characteristic of me. I'm sorry you guys had to see that shit. But if someone calls you something that offensive and that fucking disgusting, you have to bash their head with a microphone, I'm sorry."
