Law firms and financial businesses also among 19 firms in question

The Information Commissioner’s Office (ICO) has confirmed that 19 clients of rogue private detectives are to be investigated for illegal activity.

Among the firms in question are three insurance companies, five retailers, four law firms, two financial businesses, a construction firm and a security company.

According to the BBC, the ICO has asked the Commons Home Affairs Select Committee not to publish the names of the firms it is investigating.

Information commissioner Christopher Graham told committee chairman Keith Vaz MP that he believed there were 125 alleged victims of illegal activity.

The Serious Organised Crime Agency (Soca) passed the names of 102 firms and individuals who had allegedly used rogue private investigators to the Select Committee earlier this year.

Soca’s insistence that the names remain confidential proved controversial. 

Graham will appear before the Select Committee on 8 October to answer further questions about the ICO’s investigation.
