The next day the government announced that the curfew would start early at 7 pm, and warned that any rioters risked being shot. There were huge queues for public transport when workers went home early, and the city was like a ghost town one hour before the curfew. Some 3,500 police were out patrolling the streets. There were some incidents of stone-throwing in Chungking Mansions and Nam Cheong Street in Sham Shui Po. Raids by plain-clothes police culminated in the arrest of 669 'agitators'.
