The ICAC revealed yesterday that graft investigations involving newspapers other than Apple Daily are still continuing. Assistant director of the Independent Commission Against Corruption Tony Godfrey said it was looking into other corruption cases in the media sector after a reporter and two police communications officers involved in the Apple Daily bribes-for-stories cases were jailed yesterday. 'As far as this case is concerned, the matter is over. Other cases which are similar but involve other police officers and newspapers are ongoing at the moment,' he said. 'But I really don't want to go into any details, as that would just pre-warn everybody . . . and then what is the point of investigating?' Apple Daily editor-in-chief Ip Yut-kin said the newspaper had learned a lesson from the case. 'We will be more cautious in future when approving entertainment expenses,' he said. The court heard earlier that reporter Lau Kong-kwun had claimed back as 'entertainment expenses' money paid to two police communications officers for buying information. Mr Ip said the paper would keep him on the payroll while he was in jail and continue to employ him after his release. 'He [Lau] broke the law but he has undertaken to pay for his mistake by serving the jail term. We won't give him up,' he said. Hong Kong Journalist Association chairwoman Mak Yin-ting regretted a reporter had been jailed in the course of his job, but she urged others in the trade to learn a lesson from Lau's mistake.
