A police chief who played a central role in the search for Nicola Bulley earlier this year has died suddenly at his home.
Assistant Chief Constable Peter Lawson, of Lancashire Constabulary, died on Sunday at the age of 50, according to the force.
His death is believed to be "medical-related" and has been referred to the coroner.
In a statement, Lancashire Constabulary paid tribute to Mr Lawson, who they described as an "outstanding officer who served the communities of Lancashire with pride".
Mr Lawson started his career in Preston before serving all over the county in a variety of uniformed roles - eventually reaching the rank of assistant chief constable.
He appeared at press conferences during the search for Ms Bulley, who disappeared after dropping her two daughters at school in St Michael's on Wyre, Lancashire, earlier this year.
The “admired” officer started his career in Preston before serving all over the county in a variety of uniformed roles.
He was involved in the policing of many high-profile events and incidents during his career, from sporting occasions to protests and large civic and protection events.
He appeared at press conferences during the search for Ms Bulley, who disappeared after dropping her two daughters at school in St Michael’s on Wyre, Lancashire, earlier this year.
Her body was found in the River Wyre on February 19, about a mile from where she vanished while walking her dog in St Michael’s on Wyre, on January 27.
The force was criticised over its handling of the investigation and the disclosure of Ms Bulley’s personal information.
Mr Lawson also gave evidence to the Manchester Arena terror attack inquiry.
Lancashire’s Chief Constable Chris Rowley said: “This is incredibly sad and tragic news. My thoughts and prayers are with all of Pete’s family and friends at this difficult time.
“Pete’s death will come as a shock to the entire force and the wider police family across the country. He was an outstanding officer who served the communities of Lancashire with pride.
“He was also highly respected and admired by all who knew him and worked with him.
“Our deepest condolences go out to his family and we will support them as much as we can.
“We will offer support to all our staff and those who worked with Pete, as we mourn his loss."
