NBC Washington reported Tuesday that local police were investigating the appearance of anti-Semitic graffiti on the outside of the B’nai Shalom Synagogue in Olney, Maryland.

Parents arrived to drop their children off at the Synagogue's summer camp Monday morning and were shocked to discover the anti-Semitic words and symbols that had been spray-painted across the building. The vandals had not yet been caught and police were appealing to the public for information.
