Brian Keller, a well-known figure in Switzerland, has been arrested in Germany following an international warrant issued against him.

This arrest comes just a month after his release from pre-trial detention in Zurich.

The warrant was reportedly issued due to a threat Keller made during a TikTok livestream, although experts suggest his previous legal issues and conditions of release may have played a significant role.

Keller's recent legal troubles include a physical altercation with another TikToker, which led to his initial detention.

The Swiss authorities are now seeking his extradition, as the charges against him are recognized in both Switzerland and Germany.

Keller's case has drawn significant media attention, partly due to his claims of inhumane treatment during previous incarcerations, which were recently acknowledged by the Swiss Federal Court.
