The Serious Fraud Office (SFO) has carried out no raids in the year since the high-profile arrests of the Tchenguiz brothers, according to new research by Pinsent Masons.

A freedom of information request by Pinsents has revealed that from 2008 to 2010 the SFO conducted around 50 raids per year, but that none have taken place since the dawn raid of property belonging to businessmen Vincent and Robert Tchenguiz in March last year.
