An investigation into claims that an Islington detective working for a sex offences unit falsified reports has been passed on to the Crown Prosecution Service (CPS).

The detective constable, who served on the Metropolitan Police’s Sapphire Command unit, which investigates rapes and other sex crimes, was arrested on suspicion of perverting the course of justice in 2012.

The case was investigated by the Independent Police Complaints Commission (IPCC) following allegations that the officer had “falsified entries on the crime report system in relation to the submission of exhibits, advice from the CPS and authorities sought from senior officers”.

Up to 63 cases in Islington and Camden had to be reviewed and two victims were contacted over fears their cases were affected by the officer’s conduct.

The officer was interviewed by IPCC investigators on three separate occasions. He remains on bail.

Two other Met Police officers have been investigated. One, a constable, has been referred to the CPS to consider whether to bring any criminal charges.
