Frenchman in Heywood scandal returns to China 'of own free will' On Tuesday evening Patrick Henri Devillers, 52, flew from Cambodia, where he had been living, to China amid speculation that he had been offered immunity from prosecution to testify against the wife of the disgraced Chinese politician Bo Xilai. Gu Kailai, Mr Bo's wife, is the prime suspect in the suspected murder of Mr Heywood, whose body was found last November in a hotel room in the Chinese mega-city of Chongqing. At the time Mr Bo was the city's party secretary and a rising political star in China. In a 5-minute video filmed by Cambodian police authorities and posted on their official website, Mr Devillers, who is thought to have been close to Mr Bo and Ms Gu, broke his silence about his return to China. "I am now going to Shanghai, probably connecting from there to Beijing, to cooperate with the inquiry into Gu Kailai," he tells an interviewer, clutching his hands between his knees. Asked if he was travelling to China of his own volition Mr Devillers, who was arrested on June 13 at Phnom Penh villa, replied: "Yes, this is totally true. It is my will to clear things up.
