Hong Kong rioting charges filed on two

HONG KONG — Hong Kong authorities said Thursday that they had charged two men with rioting over a mob attack on protesters and passers-by in a train station in a satellite town last month. The assault led to widespread criticism of the police for their failure to stop the violence and of prosecutors for the time it took to charge anyone.

Dozens of people were injured — including journalists, protesters, a pro-democracy lawmaker and bystanders — when more than 100 men dressed in white shirts and wielding sticks and metal bars swarmed inside the Yuen Long train station in northwestern Hong Kong on July 21. On Wednesday, thousands gathered in Yuen Long to remember those injured in the attack and to call for swifter prosecution.

No suspects were arrested in the hours after the violence. A police official said none of the men were seen with weapons, despite photographs and video of officers talking to men in white shirts holding sticks and metal rods.

In the weeks after the attack, the police arrested more than 20 people, including some who had connections with organized crime. On Thursday, Kong Wingcheung, senior superintendent of the Police Public Relations Branch, sought to justify the apparent delay, saying that police sometimes do not make immediate arrests when they fear it could escalate volatile situations.

Police officials had previously acknowledged shortcomings in their response in Yuen Long, but had defended their overall actions, saying the need to send officers to other parts of the city had put strains on their response times. When Matthew Cheung, the No. 2 official in the Hong Kong government, apologized for the police response, some officers and police associations denounced him.

On Thursday, John Tse, chief superintendent of the Police Public Relations Branch, said the investigation into the attacks was continuing, but he did not discuss the possibility of additional charges.

The protests in Hong Kong began months ago over a now-suspended proposal that would allow extraditions to mainland China.
