The Hong Kong Alliance in Support of Patriotic Democratic Movements of China made the announcement today, two weeks after police issued letters to 12 members requesting information on the group’s activities and financing, according to the Post.

Chow Hang-tung, vice-chairperson of the alliance, said police did not provide a reason for needing the information, only that it “suspects the body is a foreign agent”, according to the report. The alliance “will not provide the information requested”, the Post cited Chow as saying.

The Hong Kong Security Bureau said in a statement that it noticed an organisation had stated its intention to refuse to comply with the police requirement to provide information under the National Security Law.

Authorities would follow up, and to avoid legal risk, the group should “immediately turn back before it is too late”, it said.

Failure to comply could result lead to a fine of up to HK$100,000 (US$12,870) and six months’ imprisonment, according to the Post.

The alliance will hold an extraordinary general meeting on Sept 25 to vote on its disbandment, the Post reported.

Hong Kong police are investigating the alliance for possible violations of the national security law, pro-Beijing Wen Wei Po reported last month, citing an unidentified person.
