Heidi Montag's Father Arrested for Alleged Child Sex Abuse and Incest

According to Colorado's Channel 9 News, court documents allege that Bill Montag abused a girl from when she was 13 until she was 17 in the 1990s

Heidi and Holly Montag's father is facing some serious charges.

Bill Montag, who became familiar with Hills fans when he walked Heidi down the aisle at her wedding, has been arrested in Aspen, Colo., on charges of child sex abuse and incest after the alleged victim came forward, according to Denver's Channel 9 News.

Per the station, a 29-page affidavit alleges that Montag inflicted years of abuse on a girl starting when she was 13 and continuing till she was 17. Due to a statute of limitations, he can only be charged for crimes committed since July 1, 1996, when the girl in question would have been 16.

There's said to be no indication in the court documents that either of his daughters was a victims.

The charges state, per Channel 9, that Bill abused the girl, who told authorities that she came forward to prevent other girls from becoming victims, at least 50 times.

When they were on The Hills, Holly and Heidi's mother, Darlene, was long divorced from Montag and remarried to Tim Egelhoff.

Bill reportedly worked most recently at the Aspen Valley Ski and Snowboard Club.

Heidi and Holly have yet to issue any comment on their father's arrest. A source told TMZ that the accuser "is determined to destroy the family" and Heidi and Spencer believe Bill will be cleared of all charges.
