BUDAPEST (EJP)---Unknown vandals hanged bloody pig feet on the memorial in Budapest commemorating Swedish diplomat Raoul Wallenberg who saved the lives of tens of thousands of Jews during WWII.

According to Hungarian media, a group of Jewish tourists from New York discovered the statue defaced and immediately informed the authorities.

Hungarian authorities promised "immediate action" on the case, according to the media.

Raoul Wallenberg saved the lives of tens of thousands of Hungarian Jews during the Holocaust by using his position as envoy to the Nazi occupied city to issue protective passports and shelter Jews.

He was arrested in 1945 on espionage when the Soviet Army entered Budapest. He  later disappeared.

This year marks the 100th anniversary of his birth. He was awarded the title of "Righteous Among the Nations" by Yad Vashem, the Holocaust Memorial and Institute in Jerusalem.
