Former Metropolitan police officer Peter Bleksley has advised fans planning to attend Euro 2016 that they should "dance, drink, sing, enjoy, party" at this summer's high-profile football tournament in France, despite the possibility of terrorist attack.
The French government has this week released a terror-alert app for Euro 2016, which starts on Friday, while the British Foreign and Commonwealth Office has advised fans to remain vigilant at the tournament.
Welcoming the app, which will alert users in the event of a suspected attack, Bleksley says it is important for fans not to be too concerned.
"Anything that spreads information and raises awareness is a good thing, it's only a tap on your phone away," he told Julia Hartley-Brewer.
“Just be aware and keep half an eye open for anything that appears particularly unusual.
"[The latest advice is to] run away from the attack, hide as best as you can and get on the phone and tell the authorities what is happening."
The former policeman advises not to let fear curtail people's plans.
"Unfortunately sometimes they do manage to carry out these attacks," he said.
"But there's an element of danger in doing virtually anything during the course of our lives.
"Dance, drink, sing, enjoy, party - do everything that those who want to blow us from the face of the earth don't want us to do."
The French police's app, called SAIP, will alert geo-located users to suspected attacks and offer advice on how to stay safe. It will not cause the phone to vibrate or emit any sound, and will also advise on other types of emergencies, such as floods or industrial action. It is available for both iOS and Android operating systems.
