(JTA) — Prosecutors have asked a Washington, D.C., Superior Court judge to sentence Rabbi Barry Freundel to 17 years in prison for videotaping dozens of nude women at a ritual mikvah bath.

Freundel, former spiritual leader of the prominent Washington Orthodox synagogue Kesher Israel, pleaded guilty in February to 52 counts of misdemeanor voyeurism. He is due to be sentenced May 15. In addition to prison time, Freundel could be ordered to pay tens of thousands of dollars in fines.

The rabbi, now 64, was arrested last October and charged with six counts of voyeurism after investigators found hidden cameras in the National Capital Mikvah’s shower room and in his home. He was fired from Kesher Israel, the congregation he had led for 25 years and which abuts the mikvah, soon after his arrest.

Bethany Mandel, who converted to Judaism under Freundel and has been outspoken about problems with Orthodox conversion oversight, told the Washington Post that the rabbi’s prison sentence should send a message to other would-be offenders.

“If Mr. Freundel is given a lenient sentence despite the overwhelming amount of evidence presented here it sends the message to Jewish victims of other sex crimes that it’s not worth coming forward in the future,” Mandel said.
