Bill Montag, the father of reality star Heidi Montag, has been arrested on charges that he sexually abused a teenage girl for many years.
According to a 29-page affidavit, Bill Montag - who was picked up by authorities on Thursday in Aspen - engaged in illegal acts with the unidentified minor between 1993 and 1998, beginning when she was 13 years old.
He is accused of molesting this young woman a minimum of 50 times.
Authorities say the alleged victim came forward after nearly two decades so that other potential victims could be protected from Montag.
Based on the timeline of events, the victim is neither Heidi Montag nor her sister Holly Montag.
Among other allegations, the official complaint (per TMZ) states that Bill Montag "groomed [the victim’s] with back rubs in her bedroom in the basement of their home."
The activities then escalated when he tried to insert a vibrator into her vagina. When the victim turned 16, Bill Montag reportedly began performing oral sex on her.
The documents describe the final incident as having taken place in 1998: Bill Montag allegedly crawled into bed with the 17-year old, attempted to pull down her underwear and said: "I want to have sex with you."
She rebuffed his advances and he replied with hurt, saying he thought the victim loved him the way he loved her.
Bill Montag has worked as a ski instructor and was recently employed at the Aspen Valley Ski and Snowboard Club. He divorced Heidi and Holly’s mother in 1990.
She is yet to comment on the heinous charges being brought against her father.
