Protesters Mark One Year Anniversary of Yuen Long Station Attack

Riot police patrol inside a shopping mall during a protest to mark the one-year anniversary of a mob attack on protesters and subway passengers in Hong Kong, China, on Tuesday, July 21, 2020. Hong Kong's police watchdog said in a report released in May that the delayed police response to the mob attack on citizens in Yuen Long on July 21, 2019, showed deficiencies that gave rise to rumors that police were colluding with local gangs known as triads -- but they found no evidence to substantiate that claim.
