Large numbers of police were on the streets of Hong Kong on Saturday night as officers conducted stop and searches on public transit lines and questioned residents wearing black, the colour adopted by protesters, after a mass rally dispersed to mark the fifth anniversary of the pro-democracy “umbrella movement”. Protesters changed into civilian clothes in alleys and behind walls of umbrellas in districts close to government headquarters, where earlier police fired a water cannon filled with dye and abrasive liquid from behind defensive barriers.
