By July 2007, Payet was one of the most closely surveilled prisoners in France and was never kept at the same prison for more than six months. He had been officially classified as a "détenu particulièrement surveillé," or a prisoner under especially high surveillance, and placed in solitary confinement. Despite these measures, on July 14, 2007, taking advantage of Bastille Day celebrations, four masked men hijacked a helicopter from Cannes – Mandelieu Airport. They used it to free Payet from his solitary confinement in a prison in Grasse. The helicopter landed some time later at Brignoles, 38 kilometres north-east of Toulon, France on the Mediterranean coast. Payet and his accomplices then fled the scene and the pilot was released unharmed. Two days after his escape, a European arrest warrant was issued against him.
