On her Twitter account late Saturday, she wrote: "The people at Juggalos behavior was disgusting ..." ("Juggalos" are fans of the hip-hop group Insane Clown Posse.)
Hardin County Sheriff Tom Seiner told TVGuide.com he received a report from the 28-year-old reality star over the phone about 8 o'clock Sunday morning, but she said she was unable to go to the police department to have photographs taken of the injuries.
"Myself and the state police, neither one of us have heard back from her," Seiner said.
A witness told CNN that Tequila taunted the audience at the show in Illinois' rural Hardin County, some 340 miles south of Chicago. "She took her top off and they got really violent," he said. Soon after rocks and bottles were thrown. Tequila went to her trailer, but the witness said people continued to smash the windows.
Because the festival takes place on private campgrounds, Seiner said authorities don't patrol them unless there is probable cause to come in. "In the last four years we've been in one time and that was the same night of this incident. There was a gentleman that was stabbed," he said.
The likelihood of someone being arrested for the attacks is low, the sheriff says, because " there's 800 concertgoers out there approximately this year and it's going to be very hard to identify anyone who threw that threw the things at her."
An e-mail to Tequila's lawyer was were not immediately returned.
