A skinhead Neo-Nazi spat at a holocaust survivor and gave a Nazi salute whilst another man made an obscene gesture as the 84-year-old was being interviewed on a Jewish memorial site.
Police in Germany are trying to hunt down the pair who appeared whilst Rolf Issacsohn was being interviewed by a TV crew for a documentary.
The TV crew were filming at the Leipzig Synagogue Memorial, an installation of 140 bronze seats, which sits on the site of a synagogue which was razed on the Night of the Broken Glass, in November 1938.
As the interview progressed two men appeared in the background, one with a bald head and heavily-tattooed while another man with short black hair and a black jacket.
The bald man was filmed during the interviews for the German magazine Exakt raising his hand to for a Heil Hitler salute, spat in the direction of the film crew and put up a middle finger.
He also worded "You old little p*****", according to the Daily Mail while his friend made an obscene gesture simulating masturbation while screaming "you little p***".
In response to the disgusting behaviour Issacsohn, who lost many family members to the Nazi extermination programme, said he was "shaking".
"So I have to say that I am now really shaking," says Isaacsohn, according to Vice News. "It's unimaginable that something like this happens."
German police are now trying to locate the pair, with the bald man facing a lengthy jail term as making the gesture can lead to a three-year sentence in the country.
The footage recorded by the camera team have given their material to police. It was revealed that a video surveillance camera above the memorial was actually a dummy.
Zsollt Balla, the local Rabbi, said according to the German tabloid Bild: "We notice that the mood is changing."
Police have appealed for help from the public to try and track the pair.
