In mid-2012 , Beehive Radio reported on an International Court of Justice complaint against Prime Minister Hun Sen blaming him for the 2010 Phnom Penh stampede , in which 347 people were killed . The report sparked a new series of disputes between Sonando and Hun Sen. On 26 June 2012 , Hun Sen called for Sonando 's arrest while Sonando was out of the country , accusing him of heading a separatist plot in Kratié Province to break it away from the rest of the nation . From 15 to 17 May , the province had been the site of a protest against evictions for a new rubber plant that residents accused of " land grabbing " . On the final day of the protests , soldiers opened fire on a crowd of families , killing a 14-year-old girl . Though Sonando returned during the 2012 ASEAN meeting , he was not arrested until 15 July , a few days after its end
