The Government has arranged a special flight today in anticipation of more Hong Kong people and others fleeing Indonesia ahead of mass demonstrations tomorrow. The Security Bureau ordered a special flight with a capacity for 400 passengers, boosting availability to more than 1,000 seats. It is the second time the Hong Kong Government has arranged a special flight to supplement Cathay Pacific's two regular daily flights, which can carry about 700 passengers. The extra flight was ordered because the two Cathay flights today were fully booked, a government spokesman said. Yesterday 459 people returned on the two Cathay flights, far fewer than the 719 seats booked. Yesterday, the Government urged an estimated 150 Hong Kong people remaining in Indonesia to leave immediately. Deputy Secretary for Security Sally Wong Pik-yi said the remaining Hong Kong people should take advantage of the relative calm over the past couple of days and leave the riot-stricken country immediately to avoid further unrest. 'They have not requested assistance, but we hope they also will temporarily leave,' she said. Two Hong Kong immigration officers sent to Jakarta to assist Hong Kong people are trying to call all those remaining to advise them to leave.
