Three minors have been arrested on suspicion of making threats over the Internet to one of Christine Hubbs' sex-crimes victims, the Livermore Police Department announced Wednesday.
Officers began investigating threats to one of the victims on Feb. 16, shortly after Hubbs was rearrested for a parole violation on Feb. 15.
Livermore police say Hubbs did not play a role in the threats.

Hubbs, 44, was recently released from prison after serving two and a half years behind bars for sexual relationships she had with two teen boys.
She returned to jail after she was found with possession of pornography in Hayward, according to a KPIX report.
Hubbs got the nickname "Hummer mom" because of the vehicle she drove around — sometimes with her victims accompanying her. She's being held at Santa Rita Jail in Dublin with no bail, according to court records.
