On 11 November 2009, Sivarak Chutipong was arrested by Cambodian police for passing the confidential flight plans of Thaksin and Cambodian Prime Minister Hun Sen to Kamrob Palawatwichai, First Secretary of the Royal Thai Embassy in Cambodia. Sivarak was a Thai engineer working in Cambodia for Cambodia Air Traffic Service, the private firm which managed air traffic control in Cambodia. Sivarak denied that he was a spy, and the Thai government claimed that he was innocent and that the incident was a Thaksin/Cambodian plot to further damage relations between the two countries. The Thai First Secretary was expelled from Cambodia. Sivarak demanded that former First Secretary Kamrob speak out and restore his damaged reputation by confirming he was not involved in a spy ring. Kamrob refused to provide comment to the press throughout the controversy, and Kasit's secretary, Chavanond Intarakomalyasut, insisted that although that there was no misconduct on the part of the First Secretary or Sivarak, there would be no statement from Kamrob.
