Police are searching for the people involved in the vandalism of a Brooklyn synagogue during Rosh Hashanah celebrations on Sept. 30, 2019 (NYPD)

It happened in the vicinity of Throop Avenue and Bartlett Street in Williamsburg Monday afternoon, police said.

Police said they are looking a group of people who were seen on surveillance video throwing a milk crate at the synagogue. The group returns moments later and throws the milk crate and a metal object at the windows. The building’s windows were broken during Rosh Hashanah prayers, authorities said.

Mayor Bill de Blasio called the incident an “act of hate,” and assured the community that those involved in the incident will be held responsible. 

Officers will continue to be stationed near religious institutions during High Holy Days to keep the community safe, de Blasio tweeted.

The Anti-Defamation League of New York and New Jersey said the incident was “extremely upsetting” to see the congregation targeted during a time that is supposed to be celebrated.
