Cadets rushed to the scene of a mock-car crash to help rescue a councillor who was acting as a stunt casualty.

Teenagers from Hertsmere Volunteer Police Cadets, who meet at Merryfield School, Theobold Street, Borehamwood, 'treated' Hertsmere Councillor John Donne as part of a team-building exercise.

During the four-day event at the Gilwell Park Scout Activity Centre, Chingford, the 15 young people also braved heights in a crate skating exercise, tackling a zip wire and rifle shooting practice.

As part of one exercise, they were given police radios and and asked to complete a variety of tasks – including tracking down a car registration number and getting the name of a nearby statue.

They were given an exam about criminal law and police protocol – and the highest scorers are scheduled to go head to head with other teams in a county cadet competition in June.

Cllr Donne, who represents Potters Bar Parkfield and is the president of the Hertsmere cadets, said: “It was brilliant being able to help out with the activities during the cadets’ team building weekend.

“The weekend is not just a chance to have fun, it encourages young people to try new things and push themselves.

“Above all they learnt that with the right attitude one can achieve so much more together than alone.”
