FOUR men have been arrested by Surrey Police as part of an investigation into an allegation of potential fraudulent activity at The Police Federation, which is based in Leatherhead.

The federation first raised concerns with Surrey Police and a formal allegation was made relating to the transfer of around £1million into a charitable account, in August 2015.

Two men in their 50s and two men in their 40s were arrested on suspicion of fraud under section four of the Fraud Act and conspiracy to defraud. All four men were released on bail until June 19 and June 20.

A Federation spokesman confirmed Will Riches had resigned as vice-chairman of the federation on Wednesday, but would not say why. Riches remains in his other posts, including on the Federation’s interim national board and on the powerful constables’ central committee, where he serves as a representative for the Metropolitan and City of London forces.

Leading the investigation, Detective Superintendent Karen Mizzi, said: “We are carrying out a detailed and thorough investigation into allegations of fraudulent activity involving significant amounts of money.

“As the allegation was only reported to us on March 16, our enquiries are at an early stage but specialist officers, including our Economic Crime Unit, are investigating to establish whether any offences have occurred.

“The Police Federation reported the matter to us as their headquarters is in Leatherhead and we are their local force, but to be clear those arrested are not Surrey Police officers.

“Our Professional Standards Department is currently in liaison with colleagues in relevant forces to inform them of the arrest of their officers.

“Due to the nature of the allegation, and three of those arrested being serving officers, Surrey Police has notified the Independent Police Complaints Commission and will also be in liaison with the Charity Commission going forward.

“I would urge anyone with any information which could assist with the investigation to call the Serious and Organised Team on 101, quoting Operation Rutland.
