Michel Delpuech revealed he had signed a decree authorising police and security guards to carry out the checks.

The official also said that police were drawing up a list of “sensitive” events likely to attract young spectators.

These include cinemas, theatres and sports venues – including next week’s French Open tennis tournament, which will be held at the Roland Garros stadium in Paris.

French officials have also asked organisers of sporting and cultural events to strengthen security measures following the deadly attack and to keep an eye out for “suspicious behaviour”.

Mr Delpuech added that an additional 765 police officers and soldiers had been deployed to the streets of Paris.

More than 230 people have been killed in terrorist attacks carried out by Islamist extremists in the past two years in France.

Centrist Emmanuel Macron, the country’s newly elected president, promised during his campaign to centralise information on security and counter-terrorism, and announced on Tuesday that he would be setting up a new task force against Islamic State (ISIS), the terrorist group behind the Manchester attack.
