Policeman revealed sensitive information about ongoing investigations to woman he had relationship with

The Merseyside Police officer, who has not been named, also claimed overtime on days he had spent with her on shifts and used force vehicles to pick her up.

After an Independent Office for Police Conduct (IOPC) review was launched the officer's work mobile phone was examined and statements were taken from his colleagues.

The overtime claims and use of the vehicle were also monitored.

An IOPC spokesman said: "Based on the evidence available we were of the opinion that the officer had no case to answer in respect of the woman’s allegations that he conducted a sexual relationship with her while on his shifts, or that he claimed overtime payments during times he had spent with her.

"However, we were also of the opinion that the officer may have a case to answer for misconduct for using police vehicles to conduct his relationship with the woman and to transport her during the time they had an affair, and for disclosing to her information regarding ongoing criminal and misconduct investigations.

"After reviewing our report Merseyside Police agreed that the officer had a case to answer for misconduct."

The woman contacted the force about the case in June 2017.

Merseyside Police has proposed to deal with the officer through "immediate management action supported by a documented improvement plan".

The plan will outline the officer's breaches and "expected standards of behaviour" in the future.

The case has also led to the force reviewing the management of its police vehicle keys and asking officers to carry their work radio on duty when they leave the station.

A reminder regarding the use of social media during work time has also been issued.

Detective Superintendent Dave McCaughrean said: “We received a complaint of unprofessional conduct which was referred to the IOPC.

“The IOPC concluded that the officer concerned had a case to answer for misconduct in relation to inappropriate use of police vehicles and disclosure of information.

“This has been dealt with through management action by way of advice and a written improvement plan which remains ongoing.

“Merseyside Police demands the highest possible standards from its officers and staff.

The public also quite rightly have high expectations of our officers and Merseyside Police is committed to meeting those expectations.

"The vast majority of officers who work for Merseyside Police do a really good job day in, day out and serve our communities with compassion, integrity and professionalism and we will continue to investigate, and where appropriate, refer any complaints.”
