A senior ICAC investigator appeared in court yesterday for allegedly tricking the graft-busters into granting her sick leave - on full pay and allowances - even though she was not ill. Senior Investigator Susana Chan, 42, was charged with one count of fraud and four counts of using a document with intent to deceive. She allegedly used false sick-leave certificates, which stated she was not fit to work, to mislead her supervisors at the Independent Commission Against Corruption. The commission granted her 72 days of sick leave during four separate periods between December 2002 and September last year. The ICAC also paid Chan's monthly salary, as well as all other allowances to which she was entitled, while she was off work. The alleged deception was found after an ICAC internal investigation. And upon legal advice from the Department of Justice, Chan was charged under the Theft Ordinance and the Prevention of Bribery Ordinance. Magistrate Ian Candy adjourned the case until July 2, pending transfer to the District Court.
