21 December 2020 11:50 GMT Updated 21 December 2020 11:50 GMT in London Malaysian oilfield services contractor Deleum has sought to distance itself from its four employees embroiled in a corruption probe relating to oil services and maintenance contracts for national upstream company Petronas Carigali. Deleum on Monday said the company “does not have and has never had a business strategy involving the use of alleged slush funds” and had no knowledge of the illegal scheme carried out by four employees of subsidiary Deleum Primera. “The four employees of Deleum Primera have gone on a frolic of their own to use the alleged slush funds to pay external parties and themselves, which was never authorised by the Deleum group,” the parent informed Bursa Malaysia (Malaysia stock exchange).
