Serial rapist Cheung Lai-man, who was described in various psychiatric assessments as a 'collector', launched a last-minute bid to have two pieces of evidence returned to him. The court heard Cheung wanted the police to hand back a photocopied page from a Bible with 'research' notes and a video, not of the rapes, that were seized during investigations. But Deputy Director of Public Prosecutions Arthur Luk Yee-shun, SC, told the court they were opposed to Cheung's request. 'We very strongly object to releasing these back to the accused . . . and we ask that they be destroyed,' he told Deputy Judge Alan Wright. 'It is too frightening to return the results of this [research] back to the accused.' But after a recess, counsel for Cheung, Paul Wu, said his client would withdraw his request. An order was then made that the exhibits be destroyed. There were no submissions on what was on the videotape. A report tendered by psychiatrist Dr S. H. Lui said that Cheung liked collecting things and that he 'laments the loss of the tapes [of the rapes] to the police'. The court also heard he kept trophies. He kept his first victim's underwear and from the attack on the 12-year-old he kept the tape used to gag her. In his final attack, Cheung used two video recorders to film the rape as he wanted to improve on the quality of his earlier footage.
