キュー・サムファン
On 14 November 1991, Sihanouk returned to Cambodia to participate in the elections, followed by Son Senn, a Khmer Rouge official, who arrived a few days later to set up the organisation's electoral campaign office in Phnom Penh. On 27 November 1991, Khieu Samphan also returned to Cambodia on a flight from Bangkok; initially he had expected his arrival to be uneventful, but as soon as Khieu Samphan's flight landed at Pochentong Airport, he was met by an angry crowd which shouted insults and abuse at him. As Khieu Samphan was driven into the city, another crowd lined the route towards his office and threw objects at his car. As soon as he arrived at his office, Khieu Samphan entered and immediately telephoned the Chinese Government to save him. Shortly afterwards, an angry mob forced its way into the building, chased Khieu Samphan up the second floor and tried to hang him from a ceiling fan. Eventually, Khieu Samphan was able to escape from the building by a ladder with his face bloodied, and was immediately taken to Pochentong Airport, where he flew out of Cambodia. With the departure of Khieu Samphan, the Khmer Rouge's participation in the election seemed doubtful.
