According to TMZ on Friday, Bill Montag was arrested by Aspen cops. The site did not say who the accuser was, but according to authorities, the alleged incident went on for years.

Sources connected to Montag and her husband, Spencer Pratt, reportedly told the site that the possible victim has "credibility issues." According to the site, authorities say the alleged abuse went on until the girl was 17 and the complaint says it happened at least 50 times.

The site gave some details from the documents that apparently state that Bill allegedly "groomed her with back rubs in her bedroom in the basement of their home" where a vibrator was said to be used as well as oral sex when the girl was 16.

According to the documents, there was an alleged incident where Bill crawled into bed with the female, attempted to pull down her underwear and told her that he wanted to have sex with her. According to authorities, she said, "Get the hell out of my room, no!" where his response is said to be, "I thought that's what you wanted. I thought you loved me the way I love you."

There's no word yet if this information is true since sources close to Heidi and her husband are reportedly saying that the alleged victim "is determined to destroy the family." They also say that the accuser stalked Heidi and Spencer at public appearances where security had to get her out of there.
