As part of the continuing investigation by the UK’s Serious Fraud Office (SFO) into the manipulation of LIBOR, the City of London police charged former UBS and Citigroup trader Tom Hayes with eight counts of fraud on June 18.  Mr. Hayes, one of three traders arrested last December in connection with the investigation, was also charged with fraud by US prosecutors in 2012 and threatened with extradition.  The SFO related charges are the first to be made by a UK authority in relation to the LIBOR investigation.  Press Release.
