POLICE were last night searching for a young female assistant film producer who has been missing since Wednesday. Officers yesterday conducted a door-to-door search in 21-year-old Leung Ka-man's home village of Sam Tung Uk, Tsuen Wan. On Saturday nearly 100 officers were deployed to search the area around Shing Mun Reservoir because she had told a friend she would go there looking for a site for filming. Ms Leung, who works for Westdale Interior Design, had arranged to meet a friend in a Causeway Bay restaurant at 3 pm on Wednesday but failed to turn up. A police spokesman said: 'She is said to be a good girl and has no emotional problems or financial difficulties. 'According to her friends and family, she has never gone out for one day without leaving a message.' Ms Leung is about 1.6 metres tall and has long curly hair. She was last seen wearing a white T-shirt, blue jeans and black shoes and carrying a blue bag. Police last night appealed to anyone who might know her whereabouts to telephone Tsuen Wan District Crime Squad on 417-5352, or the police hotline on 527-7177.
