AFP investigate BHP bribery claims Australian and US authorities are investigating alleged suspicious transactions carried out by BHP Billiton. THE Australian Federal Police (AFP) and US authorities are investigating bribery allegations surrounding BHP Billiton's sponsorship of the Beijing Olympics. But the mining giant insists it has done nothing wrong in relation to its sponsorship of the 2008 Games. The AFP is working with the criminal division of the US Department of Justice, which is investigating alleged suspicious transactions carried out by BHP. The AFP today confirmed it has been engaged in the matter and is working closely coordinating activities with foreign counterparts and local regulatory agencies. "The AFP has received a referral that relates to the Australian aspects of the US investigation," the AFP said. The agency said foreign bribery investigations were inherently complex and it would not be appropriate to comment any further on operational matters. The investigation has so far discovered suspicious transactions that were recorded as legitimate business payments by BHP, Fairfax Media reported. "We have been asked about BHP Billiton's sponsorship of the 2008 Beijing Olympics," BHP said. BHP's shares were 29.5 cents higher at $35.965 at 1.11pm AEDT.
