THE widow of murdered Birkenshaw policeman Ian Broadhurst unveiled a memorial stone yesterday.
Eilisa Broadhurst paid tribute to her late husband who was shot dead at point-blank range in Leeds, on Boxing Day, 2003.
The memorial stone, from the Police Memorial Trust, was placed at the junction of Grange Park Avenue and Dib Lane where the 34-year-old traffic officer was killed by former US marine David Bieber.
Pc Broadhurst and his colleagues Pc Neil Roper and Pc James Banks were shot by Beiber after they noticed that his vehicle was displaying false number plates while parked on Dib Lane.
Pc Roper and Pc James survived the shooting.
Bieber, 42, was later convicted of Pc Broadhurst's murder and jailed for life. He will have to serve a minimum of 37 years in prison before being considered for parole.
Det Chief Const David Crompton said: "The permanent memorial is an appropriate way of marking the terrible events that took place here on December 26, 2003, a day which will be remembered as one of West Yorkshire Police's darkest."
He told the congregation that the murder was "callous, brutal and cold-blooded and took the life of a completely defenceless officer".
Among the floral tributes left at the scene were two from Gordon Brown and David Cameron.
