The police have been slammed for putting a witness at 'high risk' of harm after sensitive information was released to suspected criminals.

Today (June 2) The Information Commissioner’s Office has announced that it has issued a reprimand to Thames Valley Police after details were released which led to suspected criminals learning the address of a witness.

Following the breach of the data protection law the witness has moved house, however, the impact and risk to them 'remains high'.

Head of Investigations at The Information Commissioner’s Office, Natasha Longson said: “Sensitive personal information relating to crimes needs to be handled with great care. This case shows the impact on vulnerable people if that’s not done.

“Our enforcement action in this case should act as a warning to other organisations that they must take sensible steps to protect people’s personal details.”

Upon investigation, it was found that Thames Valley Police did not take appropriate measures, such as training, to ensure officers were aware of guidance around disclosure and redaction.

The Information Commissioner’s Office added: "The force has since updated guidance and policy documents about redaction but more needs to be done."

The data protection watchdog is now recommending that Thames Valley Police provide training to all staff responsible for redactions and disclosures, share updates to policies or processes as soon as they are available and continuously review policies and guidance on the handling of personal data.
