A domestic helper accused of stealing three photos of Jacky Cheung Hok-yau and his wife while working for the Canto-pop star told a court yesterday she was a fan of his and had only kept them as souvenirs. But Preslyn-saga Catacutan, 30, admitted she had not sought her boss' permission to keep the private photos. Catacutan has pleaded not guilty to two charges of theft. The defendant, who is Filipino, is accused of stealing the photographs and a personal letter from Cheung's Repulse Bay penthouse between June and August, when the family was moving back into the house following renovations. Cheung told Eastern Court yesterday that he had no idea why the defendant had taken the photographs. 'I never give away my personal photos to anyone,' Mr Cheung said. Two of the photographs were taken when Cheung and his wife, May Lo Mei-mei, were meeting friends. The third was a passport photo of Ms Lo. He said he had been tipped off by another domestic helper that Catacutan had taken the photos, but because he needed her help in moving home he did not look into the matter immediately. Cheung told the court he sacked Catacutan on August 27, the day after completing the move to the Repulse Bay house, when she failed to give him a satisfactory explanation for keeping the photos. 'She said, 'No' when I asked the defendant whether she had taken my photos. [But I still had my doubts] so I decided to terminate her service,' Cheung said. The actor-singer told the court he called police later that day when an unopened letter addressed to him was found among the helper's belongings as she was about to leave. The letter was dated August 7. 'When I asked her why she kept my letter, she said it was a mistake - which made me call the police,' Cheung said. Police later found the three photos in a front pocket of Catacutan's jeans. Under cross-examination yesterday, Catacutan said she had planned to hand the letter back to Cheung as soon as he moved back into the home. However, it had slipped her mind after Cheung told her she was sacked. Prosecutor Karen Yuen Sui-yin told the court Catacutan had said in a statement she knew her employer was famous but she had not shown his photos or the letter to anyone. Magistrate Winston Leung Wing-chung said that, as a celebrity, it had taken great courage for Cheung to testify to the court. The hearing continues today.
