(JTA) — Vandals ripped down a Holocaust commemoration sign in Upper Nyack, N.Y.

The sign, set up Tuesday by Hebrew school students at Congregations Sons of Israel in the town in Rockland County, north of New York City, was used Wednesday evening in a ceremony marking Yom Hashoah, or Holocaust Remembrance Day, which began that evening.

It listed the number of Jews, citizens of the former Soviet Union, Poles, Roma, disabled, Jehovah’s Witnesses and homosexuals murdered by the Nazis during the Holocaust.

The sign was destroyed sometime after the ceremony. Staff discovered the vandalism arriving at work Thursday morning, a congregant wrote in the Nyack News and Views.

A police report was filed.
