Hong Kong media tycoon, Jimmy Lai, has been detained, one of seven people arrested under the new, Beijing-imposed national security law.
Lai is the most high-profile individual arrested yet under the new law.
An executive in Lai’s media group says he was arrested on suspicion of “colluding with foreign powers”; he had already been facing multiple charges for his role in the city’s pro-democracy movement.
The police also raided the offices of Lai’s newspaper.
