In another spat of anti-Semitism in Germany, police were investigating two separate incidents that occurred this week, the Jewish Telegraph Agency reported on Tuesday.
The first incident occurred in the city of Dusseldorf on Monday evening when unidentified assailants followed Rabbi Chaim Barkahn in the street and called him a "Jewish pig."

"It was a very, very terrible moment," Barkahn told the German news agency Deutsche Presse-Agentur, adding it was his first such experience in the city where he has lived and served the Jewish community for 18 years.
"Unfortunately, I can now say I don't feel safe anymore in Düsseldorf as a Jew. But I am hoping for better times," he said.
On Sunday night in Berlin, a 20-year-old man, who was also wearing a kippah, said perpetrators tried to spit on him.
Both incidents are being investigated, JTA reported.
In late May, days after Germany's anti-Semitism czar lamented that Jews would be ill-advised to wear kippot in public because of anti-Semitism in the country, one of the nation's leading dailies printed a "do-it-yourself kippah" cutout on its front page, as an act of solidarity with the Jewish community.
