in the
6 October 1976 Massacre Memorial,
Thammasat University,
Bangkok Despite his service, honesty and international reputation, Puey was branded a communist and "destroyer of unity" by the political right of Thailand. Although he spoke out against the unending student demonstrations of 1975–76 as being both ineffective and self-destructive, and even denied his students any use of the Thammasat campus as a base for mounting public demonstrations, he was nevertheless assigned blame for their occurrence. On the evening of the bloody
6 October 1976 Massacre, Puey resigned from his position as rector of Thammasat in protest against the bloodbath that had occurred that day on the university campus. Realising he was a marked man, Puey went to
Don Mueang airport where he was met by a
lynch mob. Only with the help of the Royal Thai Air Force Air Police, who had been instructed by King
Bhumibol's privy council office to help him leave, did he evade death and get on a plane bound for London. While living abroad, Puey met with Thais and influential figures in several countries, including those in the United Kingdom, the United States, France, Germany, Sweden, Denmark, Japan, and Australia to speak about the incident and to call for a peaceful transition to democracy in Thailand. In 1977, Puey gave testimonials before the
House Committee on Foreign Affairs investigating human rights in Thailand following the incident of
6 October 1976 Massacre. In September 1977, Puey suffered a
haemorrhagic stroke and was confined to a hospital for three months. The illness left Puey with a speech impediment resulting in mumbling speech. He could walk by himself, but was unable to control his right hand. Puey died in London on 28 July 1999. ==Legacy==
