A man has been jailed for life after being found guilty of murdering his ex-lover just five hours after she asked police to arrest him.
Andrew Millard, 42, who lived on a caravan park in Tewkesbury, Gloucestershire, harassed Julie Harris, 41, after she ended their affair.
He admitted manslaughter, but denied the murder in October last year.
Passing sentence at Bristol Crown Court, Judge Adrian Fulford told Millard he would face a life sentence.
Millard agreed to sign an harassment order on 5 October 2004 after the mother-of-one complained to police about his behaviour.
Two weeks later she again phoned 999 demanding that Millard was arrested.
Five hours later she was stabbed to death by Millard, who had broken into her home in River Leys, Cheltenham, and knifed her seven times in the chest.
The Independent Police Complaints Commission has launched an investigation into Gloucestershire Police's handling of the case.
A statement by Gloucestershire Police regarding the IPCC investigation said: "Following the death of Julie Harris it was identified by officers that there had been a history of incidents reported to the police by both Julie Harris and Andrew Millard.
"The Constabulary made the decision to make a voluntary referral to the Independent Police Complaints Commission.
"The outcome should be known shortly and
further information will be made public at that time."
