Director of Public Prosecutions Grenville Cross may be asked to appear before a special Legislative Council panel to address mounting concerns that the family of Zimbabwean President Robert Mugabe and their staff are 'above the law'. Members of the administration of justice and legal services panel will tomorrow debate whether to invite Mr Cross or Secretary for Justice Wong Yan-lung to field questions over the controversy surrounding the Mugabes following decisions not to prosecute two alleged assaults. The move comes after the South China Morning Post yesterday quoted a source saying two bodyguards protecting Mr Mugabe's daughter Bona were in Hong Kong on tourist visas when they allegedly assaulted two newspaper photographers outside her house in Tai Po. Mapfumo Marks and Manyaira Pepukai had earlier been spared prosecution over the February 13 incident because the Department of Justice decided they were acting out of concern for the safety of Ms Mugabe, a university student in the city. The decision followed the granting of diplomatic immunity to Mr Mugabe's wife, Grace, over an alleged assault on another photographer who took pictures of her shopping in Tsim Sha Tsui in January. Legislator Margaret Ng Ngoi-yee said she would propose at tomorrow's meeting that Mr Cross or Mr Wong should be asked to appear before the panel, possibly at a special sitting, because of the importance of the issue. 'People are seriously getting worried that the Mugabes can do what they like with immunity in Hong Kong,' she said. 'They appear to be being given not preferential treatment but deferential treatment. This is not a small matter. It is a fundamental matter of equality before the law and whether certain people can be assumed to be above the law.' Ms Ng described the revelation that the two bodyguards were apparently on visitor visas at the time of the alleged assault as amazing. 'Mainlanders and South Asians are regularly picked up for being here without a permit,' she said. 'Sex workers on visitor visas are immediately locked up until a court is free to try their case, very often locked up for months.' Michael Vidler, who represents the photographers allegedly assaulted in Tai Po, said: 'My clients are flabbergasted by this whole Mugabe affair and the handling of the matter by the department. Why are these people being given such special treatment? There are hundreds if not thousands of people in Hong Kong's prisons who have worked illegally in breach of their conditions of stay and who were duly prosecuted and punished with imprisonment. Why is the law being applied differently here?' Human Rights Monitor director Law Yuk-kai urged the government to ensure police checked on the bodyguards currently protecting Bona Mugabe, who are also understood to be in the city on tourist visas after replacing the previous bodyguards when their three-month visitor visas expired in April. 'The bodyguards involved in that case may have gone home but the government should check up on the rest of them,' he said. 'They should remind these people that they have to abide by the laws of Hong Kong.' The Department of Justice has asked police to investigate the visa status of the two bodyguards in the February 13 incident but insists it would not have affected the decision not to prosecute them for assault.
