Detective sues force for ‘psychiatric injury’ after policewoman fiancee cheats on him with colleague at the station – then sleeps with and marries the senior cop brought in to investigate

It has all the ingredients for a prime-time TV crime drama: sex games, betrayal and allegations of a police cover-up.

Because one of Britain’s sleepiest police forces is at the center of a real-life thriller – and the twists and turns of this terrifying tale will play out in court.

The case follows former detective Andrew Fearon, who sued North Wales Police for allegedly catching his fiancée, fellow police officer Rebecca Hutt, cheating on him with a colleague.

Four months before their wedding, Mr Fearon lodged a formal complaint against Ms Hutt for gross misconduct because the illicit relationship was conducted on police premises.

She also claimed he was guilty of coercive control, domestic violence and fraud.

Although an investigation was launched into Ms Hutt, Mr Fearon says it was ‘corrupt’ and was quietly shelved because – surprisingly – the senior police officer leading the investigation, Detective Steve Williams, was, Mr Fearon claims, in a sexual relationship with her at the time.

Mr. Williams later married her.

Nine years later, Mr Fearon is taking legal action against the agency.

He claims he has faced financial ruin and ‘psychiatric injury’ as a result of the ordeal and says he has been denied justice.

Details of the extraordinary case emerged from documents lodged at the High Court in Liverpool and were seen by The Mail on Sunday.

The documents allege Mr Fearon and Ms Hutt were detective constables with North Wales Police in the summer of 2017 when Ms Hutt revealed she was having an affair with a colleague, Detective Constable Shaun Parry.

They allegedly conducted their affair at St Asaph police station in Denbighshire, where they were both based, while Mr Fearon was on duty at Menai Bridge, 40 miles away.

Court documents describe Mr Parry as a ‘known sexual predator’ and reveal Mr Fearon has requested a misconduct investigation.

It is alleged that officers ‘conspired’ to take Mr Parry to a nearby station rather than discipline him.

Court documents seen by The Mail on Sunday say: ‘They [Parry and Hutt] maintained a cordial relationship at the facility. Rather than being properly dealt with as a disciplinary matter, Parry moved from St Asaph to Wrexham.

‘Parry was a known sexual predator and the defendant’s officers conspired to ensure he was not disciplined for his sexual activity with RH [Hutt].’

Mr Fearon, who took four months off work due to stress, asked his force to investigate allegations of coercive control, domestic violence and fraud against Ms Hutt, and in November 2017 Mr Williams was appointed to investigate the allegations.

One of Britain’s sleepiest police forces is at the center of a real-life thriller – and the twists and turns of the terrifying tale will play out in court.

Mr Williams concluded that no further action should be taken against Ms Hutt and she was allowed to remain in her post.

But now, while investigating Ms Hutt, it is alleged that Mr Williams was in a serious sexual relationship with her.

Court documents allege: ‘Detective Supt Williams used his rank to influence the outcome of the investigation in favor of Ms Hutt.’

Mr Fearon was furious when he learned the truth and told a colleague he wanted to arrest Mr Williams for gross misconduct.

But he claims his work fob, which allowed him access to all North Wales Police facilities, was deactivated from that evening, effectively removing him from work.

He requested that the case be investigated by an outside force, but this was also rejected and he subsequently resigned.

Mr. Williams married Ms. Hutt in 2022 and is currently retired. He is still a serving officer.

Meanwhile, Mr Parry was sacked without notice in 2019 over allegations of ‘inappropriate behaviour’ regarding another female colleague.

Mr Fearon is suing North Wales Police for £200,000 compensation for personal injury, plus a further £144,000 for loss of earnings.

The documents allege that the ‘corruption’ he was subjected to had a ‘significant detrimental impact on my physical and mental health’.

The case is expected to be heard in Liverpool court in July.

Lawyer David Miers, representing Mr Fearon, said: ‘Mr Fearon’s case centers on the failure of North Wales Police to conduct an impartial investigation in light of the alleged offenses and Ms Hutt’s relationships with other officers.

‘Failure to do this left Mr Fearon feeling isolated and unsupported, which ultimately resulted in a very serious psychiatric injury.’

Speaking at the Colwyn Bay home he shares with Ms Hutt, Mr Williams insisted he was not having an affair with Mr Fearon while he investigated her claims.

Mr Williams told The Mail on Sunday: ‘I strongly deny these allegations, which are malicious, false and persistently abusive.’

Mr Parry, who also lives in Colwyn Bay, said: ‘I have no comment on this man [Mr Fearon] and litigation.

‘I’ve moved on with my life and have no involvement.’

North Wales Police said: ‘As the matters referred to are currently subject to active legal proceedings and the hearing is scheduled for July, it would be inappropriate for us to comment at this time.’

Ms Hutt declined to comment.
