Well-known Austrian far-right, Martin Zellnerwho has been banned from entering Switzerland, was arrested on Saturday after crossing the border into Germany.

The 35-year-old, who proposes mass deportations of immigrants, was invited by the far-right organization Junge Tat (“Youth Action”), known for its anti-immigrant, anti-Islamic positions, to express himself at an event he organized in Zurich yesterday.

The Swiss Federal Police said in a decision released earlier this month that Mr. Zellner was “banned from entering the territories of Switzerland and Liechtenstein from October 10 to 27.”

He was arrested by the Swiss police in the northeastern part of the canton Thurgauin the city Kreuzlingen.

“Shortly after 10:30 a.m., a 35-year-old man was brought in by cantonal police forces in the Swiss region of Kreuzlingen and joined for further investigation,” a police spokesman told AFP.

At the beginning of the month, a representative of the Swiss Federal Police, Mr Christophe Gnagy, he told AFP that Swiss law “provides for entry bans as a police precaution when there are indications of a threat to internal or external security”.

Swiss police prevented Mr Zellner from speaking at a far-right rally organized by Junge Tat near Zurich in March and expelled him.

He was also barred from entering the Germany in March, after a rally with the far-right party AfD (“Alternative for Germany”), which had caused an outcry in the country. But a German court overturned the entry ban in May.

The “Identity Movement” by Martin Zellner posits the far-right “Great Replacement” conspiracy theory. According to this theory, there is a deliberate attempt to replace white Europeans with non-white immigrants.

Mr. Zellner does not stop at proposing the mass deportation of people who do not have Austrian nationality and are “long-term unemployed” or live in “parallel societies” that have not been integrated.
