One of Hong Kong’s most high-profile entrepreneurs, pro-democracy tycoon Jimmy Lai, has been charged with illegal assembly and intimidation.
The illegal assembly charge relates to a banned anti-government march on 31 August, which Mr Lai is accused of attending.
The intimidation charge relates to a clash with a journalist in 2017.
Two other pro-democracy figures, politicians Lee Cheuk-yan and Yeung Sum, were also arrested on Friday.
They have also been charged with one count of illegal assembly in relation to the same protest.
Senior Superintendent Wong Tung-kwong said all three men would be called to the Eastern Magistrate Court on 5 May.
