PC Darryl Street - based at the Sellafield Operational Police Unit – joined the force in 2019, after serving with Cumbria Police for a number of years.

PC Street, 59, was a married father of three adult children.

Gary Thwaite, Chief Executive of the Civil Nuclear Police Federation, said: “Darryl made a real impact at the CNC and was a valued and respected member of the Sellafield Operational Police Unit. He will be very much missed by everyone at the CNC who had the pleasure of knowing him.

“I have spoken personally to Darryl’s family to pass on our condolences from all at the CNPF and will continue to offer them all the support we can at this difficult and upsetting time for them.”

Paul Williams, Chairman of Cumbria Police Federation, said: “This is a very sad and tragic blow to Cumbria Constabulary and the Civil Nuclear Constabulary.

“Darryl worked as a police officer in North Cumbria for a number of years before transferring to The CNC to continue his career. He was a very well liked, decent, pleasant and popular officer with a shining personality.

“I have spoken with officers who worked closely with Darryl and they are very shocked and upset to hear this tragic news.”

Paul added: “This is a devastating time for his family and our thoughts go out to them.

“I have spoken with our Federation colleague Gary Thwaite in CNC who is equally shocked and saddened and we offer our full support and condolences.

“Sudden and tragic incidents like this are very hard to come to terms with and it’s impossible to imagine the pain his family must be feeling.”

Cumbria Chief Constable Michelle Skeer said:

"The sudden death of former Cumbria Constabulary Police Officer Darryl Street has left everyone within the Constabulary shocked and deeply saddened. He was an extremely well respected and popular officer.

"Colleagues who worked closely with Darryl would describe him as always going the extra mile to help others demonstrating compassion and kindness whether he was dealing with a member of the public or assisting colleagues.

"Our heartfelt thoughts are particularly with his family today and with his former colleagues within the Constabulary and his colleagues within the Civil Nuclear Constabulary where Darryl was a serving officer."
