British celebrities Bear Grylls, James Haskell, Jamie Vardy, and Jade Jones have appeared in a new anti-terrorism video aimed at young people.
In the video, they repeat the advice of "run, hide, tell" in the event of a terror attack. The guidance is: run if you are able to, hide if not, and then tell police only when it is safe to do so.
Met Police Deputy Assistant Commissioner Lucy D'Orsi, who is the national lead for protective security, told The Telegraph: "We appreciate that talking to young people about terrorism can be scary, for parents and children alike."
"But the atrocities in London and Manchester have sadly resulted in some of the youngest victims of terror this country has ever seen, and if we are able to teach children to act in a way which could potentially save their lives then it is our responsibility to do so.
"We are particularly concerned when we see people – young and old – using their mobiles to film scenes when they should be moving away from the danger. The recent incident in Parsons Green is a good example of this.
"Our research showed that many young people think filming would be a good thing to provide evidence for police. We must get them to understand that the priority must be their safety."
