Alan Butler, a former Warwickshire Police staff investigator has been sentenced to 18 months in prison after being found guilty of misconduct in public office.
The 64 year old, who worked in Nuneaton CID, entered into a relationship with a woman in 2015 while he was the lead investigator on a case where she was the victim.
Then in 2017 he attempted to form a relationship with another victim.
Superintendent Daf Goddard, head of the Warwickshire Police Professional Standards Department, said: “Butler abused his privileged position to exploit these vulnerable women and in doing so, abused trust and let down the public he was meant to be serving. We welcome the custodial sentence from the courts that reflects the grave nature of the offence committed.”
The offences were uncovered when the victims of Butler’s advances contacted police.
He has also been placed on the College of Policing barred list.
