Media tycoon Jimmy Lai, owner of Hong Kong’s Apple Daily, and pro-democracy activist Agnes Chow have been released on bail after they were arrested as part of a crackdown under a new national security law imposed by Beijing.

Lai was released in the early hours of Wednesday, flanked by his lawyers, and greeted by supporters who chanted “fight till the end” and “support apple, have an apple a day,” referring to the pro-democracy tabloid.

Lai’s bail was set at HK$300,000 ($38,461), plus a HK$200,000 ($25,805) surety.

The ardent critic of Communist Party rule in Beijing was arrested on Monday for suspected collusion with foreign forces when some 200 officers raided his newspaper’s offices and collected 25 boxes.

Journalists at the newspaper had streamed on Facebook dramatic footage of the raid.
