The incidents occurred Sunday at the FREE Synagogue and Hanna Sacks Bais Yaakov High School.
“We’ll get through it,” Rabbi Levi Notik told WFLD-TV. “I want to thank law enforcement, they did a tremendous job. They were here very quick, had detectives here in minutes.”
Vandalism also occurred at a synagogue in the Chicago suburb of Lincolnwood, WMAQ-TV reported.
A Jewish group, the Concerned Citizens League, said windows were broken Saturday at a Chicago bakery and a kosher food store.
“No official pronouncement has been made on a possible motive, but these have all the hallmarks of hate-based crimes,” said Debra Silverstein, a member of the Chicago City Council.
Police in Chicago were investigating.
