Kacee Boswell claims she joined the Falling In Reverse frontman and a group of his pals on his band's tour bus after a show in Salt Lake City on Wednesday (03Jun15), when they reportedly attacked her and took turns raping her.

She alleges she was dumped on a roadside when it was over and had to make her way to a local hospital, where the 25 year old was treated for a bruised jaw and vaginal tearing.

She subsequently filed a police report over the incident, but Radke has since spoken out to blast the accusations.

In a statement released to AltPress.com, the singer writes, "The Internet is a wonderful place because everyone has a voice. It's also an awful place for the same reason. This isn't the first time people have taken it upon themselves to spread ugly, unsubstantiated claims about myself and my friends."

He goes on to claim that he and his fellow musicians were the ones to call the cops after becoming "concerned for someone who appeared to be under the influence", adding, "No one from our band or crew were arrested in Utah... I personally spoke with law enforcement. I certainly was never under arrest or charged with any crime."

Slaves guitarist Alex Lyman has also issued a statement defending Radke, insisting he never witnessed any of the bad behaviour Boswell described.

In a message to AltPress.com, he states, "I was with Ronnie and everyone in the FIR camp the entire day of the Salt Lake City show...

"If sitting in the front lounge of your bus talking to friends and going to a bar and shooting pool with your friends until bus call is considered gang rape to you, you should maybe focus more on fixing your thought process.

"i am 200% absolutely certain that the bulls**t on the internet about ronnie is a god damn lie, he's one of the nicest and most sincere people i know. if you wanted facts, you just got them (sic)."

However, Boswell, who alleges she previously had a sexual relationship with Radke, is standing by her account of events and is encouraging other women who may have suffered similar encounters at the rocker's hands to come forward to police.

She tells the New York Daily News, "I've never felt so attacked and hurt in my entire life."

Radke is no stranger to the law - he previously served two-and-a-half years behind bars after violating his parole relating to battery charges in 2006.
