They just showed his arrest in German television. He was presented like some student organizer. However, since what they said about the Chinese security law was pretty much bs, I don't think he is a regular organizer. Plus, they obviously didn't mention that Antifas in Germany are held in custody without judgement for longer than his sentence is.
A genuine piece of shit, borderline traitor that sold out his own countrymen to bring HK back under imperialist control, he's HK's Juan Guaido
