The group made the move after police rejected its application for an annual candlelight vigil gathering in Hong Kong's Victoria Park for the second year running. The Alliance closed down the museum on Wednesday after officials from the Food and Environmental Hygiene department accused it of operating as a place of public entertainment without the required licenses. It said it had taken the decision in order to protect the safety of staff members and visitors, adding that 550 people had visited since it reopened on Sunday.
"We must carefully review the situation and seek legal advice," Alliance spokesman Richard Tsoi told reporters.
