Police paedophile investigators 'at risk of PTSD'
Police investigators who regularly view child abuse images are at risk of post-traumatic stress disorder (PTSD), anxiety and depression, researchers have said.

They have spoken anonymously to officers about their experiences in a bid to establish a better national support network.
Det Sgt Tim Plummer, who is retiring after seven years as an investigator, spoke to the BBC about his experiences.
