The American Embassy believed in March 2007 that President Kibaki's government planned to arrest opposition leader Raila Odinga over the controversial Artur Brothers, according to Wikileaks. 'Post (the embassy) has various pieces of evidence suggesting that the men are associated with either State House or one of the 'first families' and Kamlesh Pattni, the man behind the Goldenberg scandal,' said the cable from ambassador Michael Ranneberger dated 14 March 2007.
