Hong Kong Tycoon, Jimmy Lai, the most high profile person to be detained under a controversial new security law has warned young protesters they need to be more cautious.
Mr Lai was arrested on Monday and his newspaper offices raided by hundreds of police in scenes that shocked many.
Speaking after his release on bail, said he believes his arrest was just the beginning of many more to come.
He was detained with nine others over an allegations including collusion with foreign forces, under a national security law imposed by China in June.
The sweep of arrests has raised fears that China will use the new law to undertake a broad crackdown on Hong Kong’s pro-democracy activists and media figures.
