Hong Kong pro-democracy activists arrested

Police in Hong Kong have arrested four members of a pro-democracy group that had been organizing annual vigils for victims of the 1989 Tiananmen Square crackdown.

Hong Kong police on Wednesday announced the arrests of four senior members of the Hong Kong Alliance in Support of Patriotic Democratic Movements of China. Vice-chair Chow Hang-tung was among the four.

Police officials say the group failed to provide information that they had requested by a deadline. The officials say that action may be a violation of China's national security law for Hong Kong.

The alliance was banned from holding its Tiananmen vigils last year and this year.

The group's leaders, including Lee Cheuk-yan, have been jailed for organizing rallies without permission.

The police had asked the alliance to provide information on its members and activities. Officials cited as a reason the need to prevent the group from conspiring with foreign forces and threatening national security.

Chow and others visited police headquarters on Tuesday and refused to provide the information.

The alliance appears to be set to join the list of pro-democracy unions and protest organizers in Hong Kong that have been forced to disband.
