The Hong Kong reporter held in her hotel room for six hours in an apparent bid to prevent her covering a court case yesterday urged the Hong Kong government and mainland authorities to explain what happened. Hong Kong reporters were in Chengdu two weeks ago to cover the trial of rights activist Tan Zuoren, who was accused of 'inciting subversion of state power' after investigating shoddy school construction in Sichuan and remarking on the 1989 Tiananmen crackdown. On August 12, Now TV reporter Wong Ka-yu and her cameraman were stopped by police in front of their hotel as they were about to leave for the trial. Saying they had received a tip-off there were illegal drugs in their rooms, officers detained the pair and seized their identity documents. They were released more than six hours later, after a search of their rooms found nothing suspicious. They were also made to erase a video of the incident, although they successfully hid one tape that showed the start of the room search. Despite Chief Secretary Henry Tang Ying-yen saying last week the government would follow up on the incident, Wong said yesterday no official had contacted her. A government spokesman said yesterday it had nothing new to add to what Mr Tang had said. Speaking at a forum discussing the difficulties encountered by the media working on the mainland, Wong said she hoped for 'at least a proper response'. The Journalists Association and News Executives' Association plan to contact the central government liaison office in Hong Kong to reflect the media's concerns. In response to a complaint by Democratic Party vice-chairwoman Emily Lau Wai-hing, the liaison office said last week: 'We believe the rights of Hong Kong journalists to cover news on the mainland in accordance with the law will be protected.'
