A swastika and an upside-down cross were painted on a decorative post in front of a Jewish center in Miami Beach, Florida.

A security guard at the West Avenue Jewish Center discovered the vandalism early Wednesday morning, the local ABC affiliate News 10 reported.

An upside-down cross is sometimes a symbol of satanism or the occult.

The center houses a Jewish day school for boys, a rabbinical college and an Orthodox synagogue — Congregation Beth Medrash Levi Yitzchok Lubavitch. The official name of the building, which is several stories tall, is the Haim and Gila Wiener Florida Lubavitch Headquarters.

Miami Beach police spokesman Ernesto Rodriguez told the Miami Herald that detectives are reviewing surveillance video with the staff to gather more information.
