North Yorkshire Police's temporary Chief Constable has led the tributes to the officer who tragically died while on duty on Saturday 5 January 2013.
PC Andrew Bramma, 32, who was a member of the Harrogate Safer Neighbourhood Team, was killed when his patrol van hit a tree in West Tanfield, near Ripon, while he was on the way to answer an emergency call.
Andrew, who leaves a wife and two young children, had recently transferred to North Yorkshire from Greater Manchester Police, where he had served since 2008.
His family are being supported by specially trained police officers at this extremely difficult time.
All flags at North Yorkshire police stations are being flown at half-mast as a mark of respect to Andrew.
An online condolence book has been opened for people wishing to share their memories of Andrew and express their sympathy.

Officers are appealing to anyone who witnessed the collision or saw a police van travelling between Ripon police station and the scene of the incident, to contact them with information on 101.
