Clients of rogue private detectives on Soca list to be probed Nineteen clients of rogue private detectives held on a secret list of City companies are to be investigated for illegal activities, the information commissioner has confirmed. Christopher Graham told Keith Vaz, who chairs the Commons home affairs committee, that he believed up to 125 victims could have been affected by companies and individuals under criminal investigation. Mr Graham will appear before MPs next week to provide more information. The information commissioner told MPs last month that they should not publish a secret list of companies that had hired rogue investigators because this would impede attempts to bring criminals to justice. The home affairs committee and law enforcement agencies have been locked in a row over whether details of 98 clients of corrupt private eyes should be made public. Last month the committee gave the Serious Organised Crime Agency a seven-day deadline to publish the dossier but the police unit refused to do so because it would be "detrimental" to investigations. Mr Vaz and his committee are still deciding whether they should publish the list themselves. Although Soca has been collecting the names of those who used corrupt private investigators for seven years, the information commissioner only received the 31 folders of evidence from the agency in August. Scotland Yard is also investigating nine of the clients and has asked the committee to wait. Mr Vaz criticised Soca for sitting on the list for more than four years with no attempt to consider whether any of the companies should be investigated.The MP said he was very concerned that a dozen of the companies on the secret list were now inactive. [It] calls into question whether the delay has allowed illegal activity to go unpunished. Retailers, legal firms, insurers and financial business are among those who are now under investigation.
