Police chiefs have urged children and young people caught up in terrorist attacks not to stay and take pictures or videos, but to ‘Run, Hide, Tell’. A new video on the subject features Bear Grylls, Jamie Vardy, Jade Jones and James Haskell. It sets out the safety steps children and young people should take – run if they are able, hide if they are not, and tell the police once it is safe to do so. It comes after images and videos of a partially exploded bomb at Parsons Green were posted online within minutes. Children and young people are being urged not to hang around in the event of such incidents. It is the first time counter-terrorism messages have been specifically targeted at children. Police have also called for the key messages from the campaign to be routinely taught in schools.
