NEW YORK, Aug. 23 (UPI) -- Iron Maiden's manager says he knows who sabotaged the band's Ozzfest finale in San Bernadino, Calif., during the weekend.
The group was pelted with eggs and debris and the sound kept going out during the Sunday night set, Billboard.com reported.
After Iron Maiden left the stage, Sharon Osbourne came out and called lead singer Bruce Dickinson an obscenity and accused him of "belittling" her rocker husband, Ozzy Osbourne, and the Ozzfest audience.
"In 30 years in this business and after hundreds of gigs I have never seen anything anywhere near as disgusting and unprofessional as what went on that night," Ron Smallwood posted on Iron Maiden's Web site.
"The scale, viciousness and concentration of the throwing made it obvious that this was a premeditated and coordinated attack," he wrote. "Assaulting musicians while performing by throwing bottle tops, lighters and eggs at them from just a few yards away is vile, dangerous, criminal and cowardly."
Smallwood did not name anyone, but said he knows who orchestrated the sabotage.
Velvet Revolver has replaced Maiden for the final Ozzfest dates.
