An air, land and sea search continued yesterday for a KMB driver who disappeared while hiking alone in Sai Kung Country Park on Sunday. More than 100 rescuers, volunteers, friends and relatives of Wong Chak-lung, 48, resumed the search at about 9am after a fruitless search on Monday and Tuesday. A Government Flying Service helicopter searched from the air, and marine police launches and three fireboats searched the waters off the east coast of Sai Kung Country Park. On land, about 30 people searched along the waterfront, covering Cheung Tsui Chau, Tung Wan, Tai Wan and Mong Yue Kok. Another search team, involving Civil Aid Service personnel, firemen and police, combed the hills from Chek Keng to Cheung Tsui Chau. Yesterday's search ended at about 5.30pm with no sight of the hiker. Mr Wong, who has two daughters, was an experienced hiker who went hiking once a week, according to the Hong Kong Hiking website. He left he left his home in Sai Kung at about 6am on Sunday and went hiking alone in the country park. A spokesman for the Countryside Volunteer Search Team, which was also involved in the search, said Mr Wong told colleagues on a bus that he planned to hike to Cheung Tsui Chau. He left the bus at Pak Tam Au at about 8.50am. His family called the police the next morning after he had not returned home and they failed to contact him.
