The Cambodian Centre for Human Rights (CCHR) on Thursday called on the Supreme Council of the Magistracy to investigate Ratanakkiri judge Thor Saron in connection with the removal of Adhoc rights worker Pen Bonnar from the province. Pen Bonnar had advocated on behalf of ethnic minority villagers for nearly a decade until Thor Saron suggested last month that he leave the province or face prosecution on charges of defamation, incitement and terrorism. In a statement Thursday, CCHR said that suggestion may have amounted to an ethics violation.
