National security law: Hong Kong police seek activist Nathan Law and 5 others for inciting secession and collusion, insider says

Six people, including activist Nathan Law Kwun-chung and former British consulate employee Simon Cheng Man-kit, are being sought by Hong Kong police on suspicion of breaking the new national security law, the South China Morning Post has learned.

The pair, who along with two others - activists Ray Wong Toi-yeung and Lau Hong - currently in Britain, have been accused of inciting secession and collusion with foreign and external forces to endanger national security, according to a police source.

This would be the first time Hong Kong police invoked the extraterritorial provision under the sweeping law imposed by Beijing a month ago.

Responding to the news, Nathan Law said he would cut off ties with his family.

"I stress that all overseas advocacy work has been done in my personal capacity, without any political connection with other individuals," Law said in a statement. "Since I left Hong Kong, I have not been in contact with my family members. I hereby cut off relationship and future contact with them."

"I'm completely clueless to what offences I might have committed. At the end of the day, maybe the answer is: I love Hong Kong too much."

Two others, Wayne Chan Ka-kui, previously reported to be in Amsterdam, and US-based Samuel Chu of the Hong Kong Democracy Council (HKDC), were also listed as suspects since the new law was instituted.

Chu, who has been a US citizen for almost 25 years, said he had woken up on Friday to the reports that he was a "wanted fugitive". He is believed to be the first non-Chinese citizen to be targeted under the new national security law.

"The Hong Kong police is issuing an arrest warrant against an American citizen for advocating and lobbying my own government," Chu, whose Washington-based organisation has lobbied US lawmakers to support numerous Hong Kong-related bills, said in a statement.

"Let me be very clear - I might be the first non-Chinese citizen to be targeted, but I will not be the last," Chu continued. "If I am targeted, any American and any citizen of any nation who speaks out for Hong Kong can, and will be, too."

The source said that police were pursuing the six for activities that took place after the enactment of the law, which he added did not have retroactive effect.

Since the new law was instituted, several Western countries have cut off extradition treaties with Hong Kong. Even so, the source said "the move can help send a high-profile message to them or others that their acts could constitute an offence against the law".
