Hong Kong police on Tuesday detained three people under the city’s contentious national security law on suspicion of publishing content to incite others to secede from China. Authorities did not name the suspects but pro-independence group Studentlocalism said three of its members, including Tony Chung, a former leader of the organisation, were among them. The former British colony of Hong Kong returned to Chinese rule in 1997 and has been rocked by pro-democracy demonstrations in recent years.
