A former Rabbi and teacher at Eitz Chaim Hebrew day school near Bathurst and Steeles is facing sex assault charges dating back to the early 1970's.

Rabbi Heshi Nussbaum taught at the school and is alleged to have committed an indecent on a male from 1972-1975.

The victim was 12 at the time of the allegations.

It appears that Rabbi Nussbaum may have also been the choir master at the Toronto Boys Choir during the same time period, although police have yet to confirm that.

Police believe there could be more victims.
