AceShowbiz - Tool and A Perfect Circle rocker Maynard James Keenan has denied allegations he raped a 17-year-old woman at a Nine Inch Nails concert in 2000.

Calling the story a "despicable false claim", the singer has thanked fans who have shown their support and reprimanded those who retweeted his accuser's allegations.

"Many thanks to those of you who saw right through this despicable false claim that only does damage to the #MeToo movement and shame on those of you who perpetuate this destructive clickbait," he tweeted on Thursday, June 28, amost a week after the claims were initially made last Friday.

"As for my delayed but un-required response, I had my phone off. You should try it."

The accuser alleged Keenan had sex with her in his tour bus as she watched a movie with him.

"I froze so he had to move my body into a missionary position," she alleged. "He pulled off my cargo pants. He forced himself in - there was no attempt at 'warming up'.

"I mention this because this wasn't about sex. This was about raping me as fast as he could... There was no consent made. I was not high. I was clean. He did not seduce me, he forced me, quickly taking advantage of my paralyzed state."

The woman also claimed Keenan did not use a condom and gave her a strain of HPV.

She said she kept her story a secret for years because she felt no one would believe her.

Deep breath. I have to anonymously tell this story because I tried to tell it from my real account and couldn't name him directly out of fear, so I deleted the tweets. Here goes: I was 17 and he was 36. 1/

"I've carried a sense of deep shame from this assault for many years," she wrote on Twitter last week. "I thought it was my fault. How could I let him do this to me? But he was 36. I was 17. He knew exactly what he was getting away with."
