The man who allegedly beat four sleeping homeless men to death in Manhattan's Chinatown has a history of violence and a lengthy arrest record, according to law enforcement sources. Randy Rodriguez Santos, 24, was arrested early Saturday morning when police found him walking near Canal Street while carrying the alleged murder weapon - a piece of metal pipe. Police told the New York Post that Santos, who is believed to be homeless, has 14 past arrests, four of which occurred within the last 12 months. Santos was said to have been arrested in May at a Brooklyn men's shelter, where he allegedly attacked another man who was living there, using a metal object similar to the one he supposedly used to kill the four men in Chinatown Saturday. #NY

Masked pro-democracy protesters marched through Hong Kong in defiance of a ban on face coverings as the city ground to a halt on Saturday, with the subway suspended and many shops shuttered following another night of violence. Thousands of protesters staged unsanctioned marches and flashmob protests at multiple locations, a day after the city's leader outlawed masks at protests, invoking colonial-era emergency powers not used for half a century. The marches came as a group of pro-democracy politicians filed a legal challenge against the government's use of the law, which triggered an overnight rash of widespread violence - including the starting of fires and attacks on an off-duty police officer who fired a live shot in self-defence that injured a 14-year-old boy. The latest acts of resistance came after a night of widespread chaos as hardcore protesters trashed dozens of subway stations, vandalised shops, set fires and blocked roads. #HK
