A Grateful Dead concert was canceled Monday because of a rock and bottle-throwing melee in which hundreds of ticketless fans tore down fences and were confronted by police using tear gas.
Police arrested 17 people Sunday night for drug offenses and resisting law officers.
Four officers were treated for minor injuries. Twenty-five people had been arrested for various offenses earlier in the day.
The band and the Deer Creek Music Center arena decided to cancel Monday’s show because of the previous night’s violence, said Grateful Dead spokesman Dennis McNally.
“The behavior of that group of unruly fans was absolutely unacceptable and we condemn it,” said Cameron Sears, tour manager for the rock group.
On Sunday, about 3,000 fans rushed the fence surrounding the concert area, said Hamilton County sheriff’s Sgt. Eddie Moore.
