NEW DELHI, WNS: Hong Kong media tycoon Jimmy Lai was arrested on Monday on suspicion of collusion with foreign powers, his aide said, in the highest-profile use yet of the new national security law Beijing imposed on the city after protests last year.
"Jimmy Lai is being arrested for collusion with foreign powers at this time," Mark Simon wrote on Twitter.
Hong Kong police said seven people had been arrested on suspicion of violating the national security law, but the statement did not reveal the names of those arrested.
Lai, who owns popular tabloid Apple Daily, is an outspoken pro-democracy figure in Hong Kong and regularly criticizes China's authoritarian rule.
The national security law came into effect June 30 and is widely seen as a means to curb dissent after anti-government protests rocked Hong Kong last year.
Simon said police searched both Lai and his son's home, as well as other members of media group Next Digital, which Lai founded.
Next Digital operates the Apple Daily tabloid, which Lai founded in 1995, ahead of Britain's handover of Hong Kong to China. Like Lai, Apple Daily has a strong pro-democracy stance and often urged its readers to take part in pro-democracy protests.
The security law outlaws secessionist, subversive and terrorist acts, as well as collusion with foreign forces in the city's internal affairs. The maximum punishment for serious offenders is life imprisonment.
Last month, Chinese broadcaster CCTV said pro-democracy activist Nathan Law and five others were wanted under the law, although all six had fled overseas.
Law had relocated to Britain in July to continue international advocacy work for Hong Kong.
