It’s reported France manager Didier Deschamps called for an investigation after a drone buzzed their training session.
There are suggestions a drone – a small unmanned flying machine generally used to spy on military targets – flew over the training camp in Ribeirao Preto yesterday.
News agency Ansa claims many of the players joked about the drone, but that Coach Deschamps and his staff were less amused by the incident.
They fear one of their opponents in the World Cup, or even the French media, are attempting to spy on closed training sessions.
France are in Group E with Switzerland, Ecuador and Honduras.
