The Hong Kong Special Administrative Region government will use all possible means to hunt down fugitives endangering national security and would not allow them to get off scot-free, the city’s leader said on Tuesday.

John Lee Ka-chiu made the remarks at a media briefing ahead of the Executive Council meeting when asked if the SAR government has asked the Singaporean side to extradite fugitive Nathan Law Kwun-chung back to Hong Kong.

Law, a fugitive has been wanted by police on suspicion of violating the National Security Law for Hong Kong and has a HK$1 million ($127,448) bounty placed on him, had been denied entry into Singapore on Saturday after arriving from the United States, according to media reports.

“He was an absconder involved in crimes endangering national security,” the CE said during Tuesday’s briefing, reiterating that the government would hold Law accountable for his legal liabilities.

Emphasizing that no country should harbor criminals, Lee he the HKSAR government would strictly enforce the National Security Law and would go after the offenders.
