Action is due to begin this week towards extraditing a British soldier suspected of being involved in the death of an Australian construction worker. Governor Chris Patten has been kept fully briefed on the case which could see the Briton facing a post-handover trial. Police are also considering whether others indirectly involved in the killing may be charged. Gary Tait, 34, died in hospital on April 29, nine days after being beaten into a coma outside the Pussy Cat club in Wan Chai. Detectives believed Tait was involved in a dispute with a non-commissioned British Army officer who was having farewell drinks with colleagues. The soldier left for Britain two days after the assault as part of the Garrison's scheduled pullout. A source said the British Garrison had made arrangements for his companions that evening to stay in Hong Kong up to June 30 if they were needed in the police investigation. The source said: 'The extradition proceedings are expected to start in the next few days. Once the person is arrested in Britain, the Hong Kong Government will have 60 days to present the case in court.' The suspect was identified from a composite picture by the British Garrison, but the investigation has remained in the hands of the Hong Kong police. The soldier cannot be ordered back to Hong Kong by the Army but may volunteer to return. It is understood he may not have had official notification of the investigation as he is on holiday after finishing his duty in Hong Kong. Detectives believe the soldier may have to face a trial after the handover, 55 days from today. A Legal Department spokesman confirmed the police had sought advice before bringing any charges. 'We have received information from the police concerning this case and we are looking into it,' she said. 'We are waiting for some more papers, for example the post mortem report on the deceased.'
