(JTA) — Rabbi Barry Freundel, the former spiritual leader at a prominent Washington synagogue who videotaped women undressing in the mikvah, has resigned as a professor at Towson University in Maryland.

Freundel, who pleaded guilty last week to 52 counts of misdemeanor voyeurism, submitted his letter of resignation to Towson on Thursday, university spokesman Ray Feldmann told the Baltimore Sun.

His resignation is effective on March 27. Freundel had taught ethics and religion at the university since 2009 and was tenured; he was on paid leave since his arrest.

Freundel, 63, was arrested in October on six charges of voyeurism after investigators discovered secret cameras installed in the mikvah shower room and additional recording devices in his home. His Orthodox synagogue, Kesher Israel, immediately suspended him and later fired him, ordering the rabbi to vacate the synagogue’s rabbinic residence, which he has so far refused to do.

He is scheduled to be sentenced in Washington D.C. Superior Court on May 15.
