On 18 June, a group of academics and activists from the Documentation of Oct 6 Project went to Nakhon Prathom to retrieve the 'Red Gate', the rusty metal gate upon which Chumporm Thummai and Vichai Kaetsripongsa were found hanged on 24 September 1976, after they have been putting up posters protesting the return of Thanom Kittikachorn to Thailand. This incident is among the events which later spiralled into the Thammasat University Massacre on 6 October 1976.

Chumpol Thummai, Chumporn's brother, came to see off the Red Gate with his wife, Siphai. Tearfully, he said he still miss his brother, and that he wishes that Chumporn's and Vichai's souls go to a peaceful place.

Puangthong Pawakapan, lecturer at the Faculty of Political Sciences, Chulalongkorn University, said that the Red Gate will now be kept in a warehouse before becoming part of an exhibition on state violence, along with other objects belonging to those who died in the 6 October Massacre.
