Humberside Police’s outgoing chief officer is being investigated for potential misconduct, it has emerged, hours after his retirement was announced.

Mr Anderson announced he was stepping down on Tuesday less than a year after being appointed as Chief Constable.

A statement by Police and Crime Commissioner Jonathan Evison accompanying Tuesday’s announcement made no mention of any allegations and praised Mr Anderson, who took charge of the force on August 1 2023, for his "valuable contribution".

On Wednesday The Yorkshire Post received allegations relating to Mr Anderson's behaviour and complaining about perceived inaction by the Police and Crime Commissioner.

After approaching the Office of the Police and Crime Commissioner it released a statement a short time later saying they’d received “details of potential misconduct” on June 12 and referred them to the Independent Office for Police Conduct (IOPC) on Monday.

The IOPC said they’d begun an independent investigation into “allegations concerning standards of behaviour, largely related to communication and behaviour towards colleagues”.

The OPCC said: "Early yesterday (Tuesday) it was announced that the Chief Constable was retiring after 34 years of service.

"The IOPC investigation will continue notwithstanding Paul Anderson’s retirement.

"As this is now a live investigation the PCC will make no further comment."

The PCC is in discussions to get an interim in place while the recruitment process for a new chief constable gets underway.

A decision record from last July shows that Mr Evison gave Mr Anderson, who had previously served as Humberside Police's assistant chief constable and deputy chief constable, an immediate 10 per cent rise on his £158,595 salary (£15,859) as well as a car, in his new post.

The reason given was to "reflect the experience of the area and the recognition of no other candidates for the role".

The document also shows Mr Evison supported a request by Mr Anderson - who became assistant chief constable in 2019 – for a one-off payment of £12,000 in lieu of removal expenses. A freedom of information request has revealed that the request was rejected by then Home Secretary James Cleverly.

A former Humberside Police officer said: "This will be a shock to everybody in the force and out of the force so soon after he was appointed. It’s going to put the force in the spotlight for all the wrong reasons after years of improvement.” An IOPC spokesperson said: “We will now conduct a thorough investigation, independently of the police, into the matters brought to our attention”.
