The Chief Constable of Northamptonshire Police has announced he will retire in July after 30 years’ service.
Adrian Lee has led the force since October 2009 and previously worked as deputy chief constable of Staffordshire Police.
Mr Lee, who started his career at Greater Manchester Police in 1985, said he was proud of what he had achieved alongside police and crime commissioner Adam Simmonds.
He said: “It has been a huge privilege to serve as the chief constable of Northamptonshire Police.
“The force has so many amazing men and women, serving in all capacities, who share my view about the importance of vision, values and vocation in policing and work so hard to deliver the vision: to be the safest county in the country.
“I am proud of all that we have achieved together and the positive impact the force has had on so many lives.
“Strong foundations have been built for the challenges ahead.”
Police and Crime Commissioner, Adam Simmonds, who will now begin the task of appointing a new chief constable, has paid tribute to Mr Lee.
He said: “I am incredibly grateful for all his support, advice, consideration, grace and friendship over the past two years.
“He has shown considerable loyalty to our county and to the best principles of policing.
“The fine position of the force, our strategic plans and the direction of travel have been placed in such a good position through his leadership.
“I am very grateful for his dedication in making Northamptonshire Police the best it can be.
“And getting us further on the journey towards Northamptonshire being the safest county in England.”
