Prosecutors say when Cary Verse is in court Friday they will ask a judge to send him back to state prison indefinitely.
Verse, 40, was arrested earlier this month after he was accused of sexually harassing someone in his therapy class.
Verse has lived on Willow Pass Road in Bay Point for six years. He was originally convicted for assaulting four young men and boys between 1988 and 1992.
He was chemically castrated before he was released from prison.
