Several Hong Kong labour activists were taken by national security police for questioning in March. National Security Law article 63 was quoted, and they were requested not to disclose any information about the questioning. The activists are from several labour groups and also ex-members of the now-dissolved Hong Kong Confederation of Trade Unions (HKCTU). The police reportedly took phones and computers from them.
This comes just a week after the arrests of Elizabeth Tang and her sister Marilyn Tang and lawyer Frederick Ho for allegedly removing evidence from the home of Elizabeth Tang.
