A French national linked to the family of purged Chinese politician Bo Xilai has been arrested in Cambodia in relation with an unspecified alleged crime in China, The Financial Times reported. Cambodian officials and French diplomats said that Devillers had been arrested in Phnom Penh on June 13 and placed in detention, and that Beijing had requested his extradition, according to news agencies. Paris has demanded that Cambodian authorities provide an explanation for the arrest. Devillers is a 52-year old architect and long-time associate of Bo Xilai's family, having set up a UK company under the name Adad Limited with Bo's wife, Gu Kailai. Gu is now a suspect in the alleged murder of British national Neil Heywood, while the Chinese Communist Party's Discipline Inspection Commission is investigating Bo for unspecified "discipline violations."
