An Ozzy Osbourne fanatic had to be tasered by police at the rocker's concert in South Dakota on Wednesday night after refusing to curb his enthusiasm.
The unnamed 16-year-old started a mosh-pit at the front of the stage towards the end of Osbourne's set in Sioux City and security staff were forced to move in to stop him from injuring other audience members.
The teenager ignored security men, who then left police to deal with the over-excited youth.
When he refused to calm down and after he injured a police officer, he was tasered and removed from the audience.
The teen now faces a date in juvenile court on misdemeanor charges of interference with official acts, failure to obey a police officer and assault on a police officer.
