Macau police have arrested prominent pro-democracy figure Au Kam San on suspicion of colluding with foreign forces. Authorities allege that Au has been in contact with an unspecified 'anti-China organisation abroad' since 2022. The arrest has raised concerns about the shrinking space for political dissent in the region and the increasing application of national security laws to silence opposition voices. Details regarding the specific nature of the alleged collusion and the identity of the foreign organisation remain undisclosed.
