Police recruits in Kent are among the first in Britain to train with other organisations to give them a better idea of what they could encounter.

The trainees are being placed with everything from fire crews to homeless charities as part of their training.
Yasmin Mossadegh, 22, a student at Canterbury Christchurch University, said working with the ambulance service had shown how everyone worked together.
Kent ambulance worker Steve Tucker said it gave police a better understanding.
"It's not going to be so much of a shock," he said.
Kent probationers were also among the first in Britain to be trained at university, and to go on placements.
