Three men have been arrested for the murder of a Mongolian who was found collapsed with wounds to his body in a guest house in Chungking Mansions. The body of the 29-year-old man was found on Tuesday by an employee of the Disney Deluxe Guest House on the 14th floor of the 17-storey building on Nathan Road, Tsim Sha Tsui. A police spokesman confirmed the arrests but would not give any further details. An officer close to the investigation said the arrest was made after officers reviewed CCTV videotapes taken from the guest house. He said more arrests might be made and officers were still trying to find a motive for the murder. An autopsy on the Mongolian failed to determine the cause of death and more tests will be carried out. The body has yet to be identified. The room was still cordoned off yesterday and police questionnaires had been issued to those in the building as part of the investigation. Chungking Mansions - the five blocks housing 100 guest houses, 800 flats and three floors of shops including a number of South Asian restaurants - has variously been described as 'a centre on the edge of society', a 'towering inferno waiting to happen' and an 'eyesore deserving nothing other than demolition'. But much has changed since the buildings went up in 1962. A facelift five years ago, the installation of closed-circuit television and the addition of security guards has reduced crime and helped Chungking Mansions to clean up its image. It was formerly often associated with gangs, violent crime, vice and murder. In August 2002, a 41-year-old Indian woman was murdered in one of the guest houses there. A tourist, she was found dead in her room with multiple cuts and stab wounds to her head, neck, waist and back. In March 2002, a guest-house employee was stabbed to death in a suspected revenge attack. The body of the Pakistani victim, 38, was found in a corridor on the ground floor. He had been stabbed three times in the neck. In July 2001, an elderly owner of a guest house in the complex was found dead on his bed with his hands and legs bound with tape. And in June 1999, the body of a Bangladeshi businessman, Razzak Mohammed Abdur, 31, was found bound in a garbage bag in one of the guest houses.
