Sean Price became Cleveland chief constable in 2003
The chief constable of Cleveland Police has had his contract extended for a further four years.
Sean Price, 52, took the helm six years ago at a time when crime was rising and the force had a huge cash deficit.
Recent figures suggest recorded crime has fallen in the force area by about 20% over the past 12 months.
The officer, who began his police career in Merseyside in 1979, said he was "delighted" to be staying on Teesside until at least March 2013.
Cleveland Police Authority chairman Dave McLuckie said: "We are absolutely delighted that Sean is staying.
"The progress made during his period at the helm is remarkable.
"The most important achievement is that we have been winning the battle against crime.
"By the end of the current financial year, we are on target to have cut recorded crime by 20% - equivalent to well over 11,000 fewer victims of crime."
"We appreciate he is deeply committed to continuing to build on the progress which has been achieved over recent years and indeed has made it clear that he has no wish to serve with any other force."
Mr Price said: "I am absolutely delighted with the support I have received from every member of the force during my time with Cleveland.
"I am delighted with the extension to my contract and look forward to continuing for at least another four years."
