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.

Earlier this year the Tchenguiz brothers won the right to a judicial review of the circumstances surrounding the raid after the SFO admitted to mishandling the case, which has so far handed related legal roles to firms including Stephenson Harwood and BCL Burton Copeland.
