A 31 year-old tourist was attacked in Berlin last week, according to the Judisches Forum fur Demokratie und gegen Anti-Semitism (Jewish Forum for Democracy and Against Anti-Semitism), during the Rosh Hashanah holiday.
At about 6:00 pm Thursday, the organization stated, an attacker shouted anti-Semitic insults at the tourist and mugged him, snatching the Star of David necklace he wore around his neck.
The attack occurred in the Kreuzberg district, local De Welt added, in Gorlitz Park.
Germany's national police have launched an investigation into the incident, it said.
Anti-Semitism throughout Europe reached record highs during the past few months as incitement and attacks against Jews - mostly led by Muslim the extremists, but also elements from the far-right and far-left - left Jewish communities throughout the continent in a state of shock.
Germany's Jewish community in July, at the height of the fighting between Israel and terrorists in Gaza, condemned an "explosion of evil and violent hatred of Jews" at pro-Palestinian rallies where some demonstrators chanted that Jews should be "gassed".
The spate of ugly incidents that deeply unsettled Germany's resurgent 200,000-strong Jewish community also saw a petrol bomb hurled at the facade of a synagogue in the western city of Wuppertal. Three people, described as "Palestinian" nationals, have been arrested in connection to that attack.
Anti-Semitism has become so high recently that German Chancellor Angela Merkel, along with Jewish leaders, spearheaded a rally in a central Berlin square against Jew hatred earlier this month.
