A jewellery shop manager in Wan Chai narrowly escaped injury when he unwrapped a parcel wired to blow up in his face. The parcel, which began to emit smoke when it was opened, contained a videotape box packed with seven plastic bags of inflammable liquid, three lighters and wires. The manager of Emperor Watch and Jewellery Company's branch in the Emperor Group Centre, Hennessy Road, received the parcel wrapped in red paper after 1 pm. Smoke began to billow from the package when it was opened on the counter. 'Someone yelled it was a bomb and then we immediately ran out of the shop,' a staff member said. There were about 10 employees in the shop and no customers. 'Luckily, it did not burst into flames,' said Chief Inspector Douglas Shearer. 'We've taken the device away for tests. 'It was quite a professional device.' Senior Bomb Disposal Officer Dominic Brittain said: 'It's an improvised incendiary device which can cause fire and severe injuries to the hands, face and body of the person who opens it.' Police evacuated people from the first four floors of the shopping arcade and cordoned off a section of Hennessy Road and nearby roads for hours. Emperor Group chairman Albert Yeung Sau-shing is a director of Emperor Watch and Jewellery, which has four branches in Hong Kong. A spokesman said he had no comment. Detectives said they would look into every possible motive for the failed attack, including personal grievances against staff members or Mr Yeung. Mr Yeung was cleared of accusations of criminal intimidation and false imprisonment in May 1995 after five prosecution witnesses failed to recall details of the alleged offences. Five months later, he was acquitted of an allegation of attempting to pervert the course of justice. Police believe yesterday's case is unrelated to the 500-gram bomb found at the New Flower City Nightclub in Hilton Towers, Tsim Sha Tsui, on Monday. Organised Crime and Triad Bureau officers last night continued sending out questionnaires to nightclub workers, hoping for information on the case.
