(JTA) — A biker brandishing a knife and shouting anti-Semitic slogans in front of Vienna’s main synagogue was arrested.

The biker, identified as Markus G., 51, was taken into custody by Austrian police on Oct. 4, the news site oe24.at reported.

According to the report, the man assaulted police when they approached him but he did not hurt anyone prior to his arrest. His demeanor suggested he was inebriated but he refused to undergo an alcohol test.

In 1981, two people who had attended a bar mitzvah ceremony at the synagogue were murdered and 30 were injured in an armed attack by Palestinian terrorists.
