Hikers, rescuers stranded overnight on Tai Po hill A group of hikers and four firefighters sent to rescue them were trapped overnight on a Tai Po hill. Twenty one hikers - 10 men and 11 women aged 10 to 77 - set out on a trek at Tai Mo Shan Country Park at 10am on Tuesday. They lost their way and called 999, using a mobile phone at about 7pm. A Government Flying Service helicopter spotted them near Yim Ngam and airlifted a 77-year-old woman to Chek Lap Kok airport at about 9.30pm. She refused to go to hospital and went home. An hour later, a four-man team from the Fire Services Department found the other 20 hikers, but because of darkness had to call off the helicopter. The helicopter returned at 7am yesterday and airlifted everyone to the airport. property firm manager leaps to her death A businesswoman leapt to her death from her office in Central - one of three people who committed suicide yesterday. The 44-year-old woman, who ran a property firm, was found unconscious outside World Trust Tower in Stanley Street at 10.30am. She was taken to Queen Mary Hospital where she was declared dead. Police believe she jumped from her sixth-floor office. In a second case, a 30-year-old man jumped to death from his 12th-floor flat in Hiu Kwong Street, Sau Mau Ping, shortly before 12.30am after a row with his mother, 54, over money. The third victim was a 42-year-old man who jumped to his death from the fourth-floor car park in Shui Che Kwun Street, Yuen Long at about 9.30am. Police said a note was found in his Yuen Long flat asking his wife to look after their daughter.
