(JTA) — A Greek doctor who posted a “Jews Not Welcome” sign outside his office was arrested for inciting racial hatred.

The doctor, a 57-year-old neurologist from Thessaloniki, also was charged with weapons possession and pro-Nazi beliefs, according to the Greek Reporter.

The sign was written in German. The doctor, who has not been named, is a member of the Greek ultranationalist Golden Dawn party and an avowed Nazi supporter, according to reports. The party is known for its Nazi swastika-like flag and Holocaust-denying leadership.

Police found three daggers, 12 knives and pills without prescriptions at the doctor’s home. Two of the daggers were engraved with Nazi symbols.

The Jewish community of Thessaloniki was an important center of Sephardic Jewry for 450 years following the expulsion from Spain. It had a pre-World War II Jewish population of 55,000; now about 1,000 Jews live there.
