Investigators have searched two addresses in Nottingham as part of continuing efforts to clamp down on unlawful activities in the personal injury sector.

Enforcement officers from the Information Commissioner’s Office executed warrants on the properties as part of an investigation into what it said was a network suspected of making hundreds of millions of nuisance calls.

The raids, which were coordinated alongside the Claims Management Regulator and Nottinghamshire Police, were on an office building and a house.

The ICO said it believes the network is responsible for ‘bombarding’ UK citizens with unsolicited automated calls promoting personal injury claims.

Computer equipment and documents were seized for analysis and the ICO’s enquiries into alleged breaches of the laws surrounding unsolicited telephone marketing continues. There were no reports of any arrests following the searches.

The Claims Management Regulator, part of the Ministry of Justice, is also investigating potential breaches of the Compensation Act 2006.

Andy Curry, ICO enforcement group manager, said: ‘People are sick and tired of receiving nuisance calls. The evidence we had already gathered prior to these warrants suggests this network, operating both in the UK and overseas, is responsible for making hundreds of millions of them.

‘We hope the material we have now recovered will help identify other organisations and individuals in a lengthy and complex investigation, and assist the ICO and our partners in taking enforcement action.’

The news comes days after the SRA expressed its concerns about the links between personal injury firms and companies working in the claims management industry. A review of the sector found some firms were not adequately training staff or not carrying out enough checks at the outset of claims to reduce the risk of fraud, the regulator said.
