A German far-Right activist was arrested in Hungary on Wednesday on suspicion of illegally selling guns over the internet, marketing them as “migrant deterrents”.

Mario Rönsch was held on a European extradition warrant issued by his native Germany. He has been on the run from the German authorities since 2016.

He is accused of running a website called Migrant Deterrent, which sold more than €100,000 (£87,000) worth of unlicensed weapons to customers in countries across Europe under the slogan: “Simple, fast and discreet: that's the mantra of Migrant Deterrent”.

Although most of the weapons were gas-powered, which meant they were legal in Germany, they were sold without the necessary licenses.

Customers were also supplied with banned lethal ammunition, possession of which is punishable by up to five years in prison.

The website portrayed migrants as potential rapists and marketed the weapons as a “defence against ficki-ficki specialists”, employing a racially pejorative term used to imply that migrant men harass women for sex.

The guns were also advertised as “opinion enhancers against rogue leftists”.
