Society for Threatened Peoples
In August 2011 the Society for Threatened Peoples and "TRIAL - Swiss Association against Impunity" filed a criminal complaint with the Public Ministry of Switzerland against Dias for alleged war crimes. Dias dismissed the war crimes allegations as "baseless, unfounded and non-substantiated allegations. Fictions, not facts". The Swiss government subsequently confirmed it had discussed the alleged war crimes with Dias. On 14 September 2011 Dias was recalled to Sri Lanka. The Sri Lankan government claimed that he was returning to Sri Lankan because his two-year term had come to an end but reports in the media suggested that he had been stripped of his diplomatic immunity and the recall was to prevent war crimes charges being filed against him. The Swiss federal prosecutor has announced that a criminal investigation against Dias would commence if he ever returned to Switzerland.
