A $100,000 bribe given to rebuild Villawood after riot A COMMONWEALTH official took bribes to influence the tendering process for contracts worth millions to rebuild parts of the Villawood Detention Centre damaged during the detainee riots. Jason Patrick O'Halloran corruptly received almost $100,000 cash from two western Sydney construction companies as kickbacks for information that would help them win the work, a court has heard. The jobs included rebuilding nine buildings burnt down during the April 2011 riots where detainees caused $6 million worth of damage. The 34-year-old from Hornsby pleaded guilty to two counts of receiving a corrupt benefit as a Commonwealth public official and was being sentenced in the Sydney District Court on Friday. In June, four detainees were jailed over the riots. Pictured is a common lounge and dining room, during a tour of the Sydney Immigration Residential Housing area of Villawood Detention Centre. O'Halloran worked as a contractor for Serco Australia which has a contract with the Department of Immigration and Citizenship to manage the detention centres. According to a set of facts tendered to the court, O'Halloran admitted to corruptly organising to receive almost $60,000 from Michael Klapsogiannis, the managing director of Seven Hills-based Vantagecorp. Klapsogiannis has been charged with two counts of bribing a Commonwealth official. He hasn't entered a plea. But his lawyer John Sutton indicated he would fight the charges. O'Halloran also admitted taking about $30,000 cash and an 18-year-old bottle of Chivas Regal from Mohsen "Mick" Elsalim, the managing director of Bass Hill-based Blue Star Building Services. Elsalim has also been charged with bribing a public official. He hasn't entered a plea and it is understood he will fight the charge. O'Halloran surrendered $90,000 to investigators and will return to court next month.
