The Georgetown rabbi who pled guilty to 52 counts of voyeurism is going to prison.

Barry Freundel was sentenced to six and a half years in prison Friday after secretly videotaping Orthodox Jewish women, including an alumna, as they took ritual baths, according to The Washington Post. Freundel is also required to pay $2,000 in fines, The Post reported.

Senior Judge Geoffrey Alprin of the D.C. Superior Court sentenced Freundel after hearing hours of testimony from the women he filmed.

“You repeatedly and secretly violated the trust your victims had in you and you abused your power,” Alprin said in the Post report.

Prosecutors said during his hearing that Freundel filmed nearly 150 women through a camera hidden in a clock radio as they took ritual baths in the Kesher Israel synagogue in Georgetown. Stephanie Doucette, an alumna, confirmed in February that she was also recorded by Freundel.

Freundel taught religion classes as a part-time faculty member at GW until as recently as 2008, and led services at the synagogue, located on 28th and N streets.
