The killer of constable Leung Shing-yan was 'cold-blooded and cruel', police chief Tsang Yam-pui said yesterday after visiting the murdered policeman's grief-stricken family. A top-level force delegation, led by Mr Tsang, met the dead officer's tearful mother, his fiancee and other family members at their home in Cheung Shan Estate in Kwai Chung yesterday. Deputy Commissioner of Police for Operations Lau Yuk-kuen, Deputy Commissioner of Police for Management Lee Ming-kwai, and four chairmen of police staff associations were also there to express their condolences. A visibly angry Mr Tsang said after the visit: 'I would like again to strongly condemn the cold-blooded and cruel murderer who killed our policeman. We will do our best to solve the case.' The 23-year-old constable was shot dead with his own gun after he was lured to an empty flat in Shek Tau Estate in Kwai Chung to handle a noise complaint on Wednesday. Mr Tsang described Leung as brave and responsible, and praised his excellent performance during his time in the force. He confirmed a funeral with full honours would be held for the officer on March 26. 'I have discussed funeral arrangements with the family and they are satisfied,' he said. Mr Tsang has obtained approval from the Civil Service Bureau for the permanent burial of Leung in the Gallant Garden in Wo Hop Shek, Fanling - the cemetery for civil servants killed on duty. 'The incident highlights the danger which all frontline workers have to face, and reminds us to be careful while performing duties,' he said. Tony Liu Kit-ming, chairman of the Local Inspectors' Association, said lack of communication was a problem and that manpower shortages were putting frontline workers in danger. Mr Tsang said communication problems could not be avoided in such a big organisation. 'We have certainly made every effort to improve communication from the bottom to the top, but of course we cannot say it is perfect.'
