The Hong Kong police said Friday that they had arrested 37 protesters accused of blocking five roads in the Mong Kok neighborhood and disobeying orders to disperse. They arrested 12 protesters overnight Wednesday in the same area, which democracy advocates had occupied for more than two months before being dispersed. Protesters have been demanding that residents of Hong Kong be allowed to elect their top executive in 2017 from an open list of candidates. The central government requires that candidates be selected by a committee that it controls.
