Ozzy Osbourne's touring Ozzfest show has been marred by another controversy after an off-duty police officer was attacked while trying to make an arrest on Tuesday night (28Aug07). According to North Carolina police, one officer suffered minor injuries in a scuffle at the Verizon Wireless Amphitheatre show in Charlotte, where he was working as a security guard. The authorities claim several off-duty officers, who were working as security guards at the concert, were assaulted by a fan, and had to use force to arrest him and take him into custody. But police officials insist this was one incident during an otherwise trouble-free event. Two people died and 83 were arrested at Ozzfest's Holmdel, New Jersey stop on 16 August (07). The Ozzfest dates end on Thursday (30Aug07) in West Palm Beach, Florida.
