Lesley Hart was off work due to stress when she competed on the BBC show, hosted by Richard Hammond and Amanda Byram, last year. The 51-year-old was flown to Argentina to complete the challenging obstacle course in an episode broadcast last May, The Daily Telegraph reports.
Following complaints from colleagues, Hart was cleared of misconduct after an internal investigation by Devon and Cornwall Police. However, she was deemed unfit to return to her job by occupational therapists and was medically retired. She is now suing the force, claiming that she was not provided with enough support.
"Lesley now realises it was a big mistake to go on the show and she only survived two challenges anyway," a friend said. "She saw it as being within the remit of her recuperation but some people in the police took a very dim view of it.
"Even before it was broadcast she knew it was the wrong thing to do. When other people saw it they knew she was off sick and put two and two together and made five. It is not the case of someone who was swinging the lead and was caught out by going on a TV game show."
A Devon and Cornwall Police spokesperson commented: "While we do provide our staff and officers with support when they are experiencing sickness or difficult circumstances, we are unable to offer any comment in relation to Ms Hart at the current time due to ongoing legal proceedings."
Emma Boon of the Taxpayers' Alliance said: "If she was well enough to take part in a game show in Argentina the public would be forgiven for thinking that she was well enough to work. It adds insult to injury that she is now trying to sue the force and take even more taxpayers' money."
The paper added that neither Hart, of Newton Abbot in Devon, or her solicitor were available for comment.
