A Polish national living in Germany and identified only by the name “Marius” was arrested for erecting a replica of the gate to Auschwitz in front of a German tax office in the Bavarian town of Eggenfelden.

The replica bore the famous slogan “Arbeit macht frei” and was so exact that the “artist” even placed the “B” upside down, as it appears in the original. He also added wooden swastikas and a chimney smokestack with the words “Zyklon B,” a reference to the gas used in the killing chambers of Auschwitz to murder the vast majority of the one million Jews who did not survive the death camp.

The mother of the detainee, who works as an advertising manager, said that her son is not an antisemite, just depressed. He had incurred an overwhelming tax debt, a situation that enraged him and threw him into despair.

Critics note that depression does not manifest as Jew hatred, unless the mentally ill person is already a Jew hater.

The act violates Germany’s strict laws on incitement to hatred and using Nazi symbols, prompting an investigation into the 33-year-old man who erected them back in April. Upon his arrest, authorities found more Nazi symbols in his home.

Eggenfelden’s mayor, Martin Biber, blasted the actions as “disgusting insolence” and “an insult to society.”
