SFO probes new claims over Bumi's missing £48m It is not yet possible to establish the veracity of these claims. The SFO officer replied to the source saying, "I have been reviewing the information that you provided together with my colleagues," adding that it is "considered extremely valuable." However, he stressed that "the activity you describe is predominantly outside of the UK" and "I am not in a position to disclose to you what activity we may or may not take." Bumi, which has written off the $75m, is known to be pursuing the manager of the Chateau fund, David Boren. The source alleges that, under instruction from superiors, he "concocted" quarterly investment management reports on Chateau "solely for the purpose of passing the due diligence" necessary to list Bumi in London. Mr Roeslani, who is also the former chief executive of Berau, quit last December as a Bumi non-executive after the Takeover Panel ruled he was a member of a shareholder concert party with the Bakrie family that should have been disclosed. He was replaced as the boss of Berau in January. The $75m missing from Chateau has become a major bone of contention between Mr Rothschild and the Bumi board. In December 2011, he emailed Bumi's former finance chief, Andy Beckham, and audit committee chairman Lord Renwick, noting sarcastically that the "star fund managers at Chateau" must have invested in some "fairly low quality assets" as Berau had already written down the investment by $20m. As the extent of the losses from the Chateau investment became clear, Mr Rothschild went on to demand of chairman Samin Tan and senior non-executive Sir Julian Horn-Smith: "Why has action not been taken against the perpetrator (s)?." Bumi, which declined to comment, was forced to suspend its shares after delaying the publication of its full-year results following the discovery of a further $94m of accounting issues at Berau. Mr Roeslani did not respond to emailed requests for comment. Mr Boren could not be reached for comment. The SFO declined to comment.
