Hong Kong protesters organise flashmob to support Apple Daily newspaper's owner and activists arrested under the national security law.

Footage from Tuesday (August 11) in Langham Place mall, Mongkok shows protesters exhibited copies of Apple Daily while chanting slogans.

On Monday (August 10) Jimmy Lai, the owner of Apple Daily newspaper was arrested under charges of "collusion with foreign entities," for allegedly demanding sanctions against Hong Kong and China.

Riot police eventually entered Langham Place to disperse protesters who continued chanting outside.
