Bo Xilai scandal: China 'offers immunity to Patrick Devillers' Speaking to AFP on Tuesday, a spokesperson for Cambodia's interior ministry, Khieu Sopheak, suggested Mr Devillers - who has not formally been accused of any crime in China or Cambodia - could receive legal immunity if he co-operated with the Chinese inquiry into Mr Bo and Ms Gu. China has requested to take him there to help the investigation and has guaranteed they would not prosecute him. He hasn't made a decision yet. It is up to him to decide. Cambodian authorities last month said they would not extradite Mr Devillers to China but are they still holding him in the capital Phnom Penh. Last month Cambodia's Information Minister told reporters he believed Mr Devillers was "keeping money" for Ms Gu who he is first thought to have met during the 1990s while living in Dalian, the city where Mr Bo was mayor. Japan's Asahi Shimbun newspaper has claimed Ms Gu has admitted to killing Heywood after he threatened to expose an illegal scheme to channel some $6bn out of China.
