Police Raid Already Closed June 4 Museum

National security police raided the now-closed June 4 museum in Mong Kok on Thursday, as four core members of the Hong Kong Alliance in Support of Patriotic Democratic Movements of China, which ran the venue, remained in detention.

Officers arrived at the museum on Thursday morning to search for evidence, and cordoned off the entrance to the building.

They were later seen loading a truck with bits of cardboard, including one bearing the museum's logo and another carrying a picture of a lit candle.

The alliance, which used to hold annual June 4 candlelight vigils, closed the venue in June after officials accused it of operating the site without the required licences.

The group pleaded guilty in court and was fined HK$8,000.

Vice-chairwoman Chow Hang-tung and three other members of the alliance were arrested on Wednesday on suspicion of failing to provide information as instructed by national security police.

The force alleged that their refusal contravenes article 43 of the national security law which states that suspects can be required to answer questions and hand over "material relevant to an investigation".
