Bill Montag, the father of "The Hills" star Heidi Montag, was recently arrested in Colorado on charges of sexual child abuse and incest, People reports.

Montag was arrested at his place of work at Aspen Valley Ski and Snowboard Club, and has since been suspended from his job following the sexual abuse allegations.

A press release from the Aspen Police Department has been obtained by People and reads that Montag has been charged with "three counts of sexual assault on a child by one in a position of trust, and one charge of aggravated incest."

If convicted, Montag faces up to 12 years in prison and a fine ranging from $3,000 to $750,000," says People.

TMZ reports that the Montag allegedly abused a 13-year-old girl over 50 times from 1993-1998. Although the victim has not been identified publicly, TMZ claims that Montag's victim was not one of his daughters, Heidi and Holly.

The court documents obtained by TMZ read that Montag allegedly "groomed" the victim "with back rubs in her bedroom in the basement of their home," and escalated by attempting to insert a vibrator into her vagina. At age 16 he began performing oral sex."

The documents also detail the final time Montag abused the victim when she was 19 in 1998. Montag allegedly "crawled into bed with her, tried to pull down her underwear and said, 'I want to have sex with you.'"

The victim responded, "Get the hell out of my room, no!" And he responded, "I thought that's what you wanted. I thought you loved me the way I love you."

Neither Heidi nor her sister have spoken publicly about the accusations against their father.

However, TMZ sources claim that the girls believe the alleged victim is lying and attempting to ruin their family.

"They say she has stalked Heidi and Spencer at various public appearances to the point security had to remove her," says a TMZ source, adding, "Heidi and [her husband] Spence believe Bill Montag will be exonerated."
