LIVERMORE (CBS/AP) — A Livermore mother sentenced to five years in prison for having sex with two underage boys is back behind bars after being arrested on an alleged parole violation.

44-year-old Christine Hubbs was arrested late Friday and remained in jail on a no-bail hold, according to the Department of Corrections and Rehabilitation. During a parole compliance sweep, Hubbs was found to be in possession of pornography, which was in violation of her parole conditions, according to Fredrick Bridgewater, CDCR Assistant Regional Parole Administrator.

In 2011, Hubbs pleaded no contest to one count of unlawful sexual intercourse with a minor under 16 and three counts of lewd acts on a child.

She was required to serve half of the five-year sentence in a plea deal which included three to 10 years probation. The plea deal also required her to register as a sex offender.

Hubbs became known as the ‘Hummer Mom’ for the SUV she drove the teens around in. Investigators say she had a sexual relationship with one of the boys starting in December 2008 when he was 14. The other relationship was with another 14-year-old boy and occurred for several months.

In another development in the case, a Livermore police officer told the Livermore Patch that one of Hubbs’ victims has been the target of cyberbullying.
