PTU head Fung Wai-wah said many parents are emigrating overseas amid safety concerns, as a newly established force of national security police have been arresting people for peaceful political activities deemed harmful to Hong Kong. In January, 47 pro-democracy activists and former opposition lawmakers were arrested on suspicion of "subversion" under the national security law, for taking part in a democratic primary election that was designed to maximize the number of opposition seats in the Legislative Council (LegCo).
Chief executive Carrie Lam responded by postponing the LegCo elections until December 2021, prompting the mass resignation of the rest of the opposition camp.
