Seni's government came under great pressure. A bill to extend elections to local levels was passed by parliament 149-19, but the king refused to sign the bill or return it to parliament, effectively vetoing it. As anti-leftist sentiments mounted, Praphas Charusathien returned shortly from exile and met the king. Students protesting Praphas' return were attacked by Red Gaur paramilitary units. On 19 September 1976, Thanom also returned from exile and was immediately ordained as a monk at Wat Bovornives. Massive protests erupted. The king and queen returned from a trip to the south and visited monk Thanom, leading Seni to resign from the premiership in protest. His resignation was refused by parliament, but initial attempts to reshuffle his cabinet were vetoed by the king. The political tension finally culminated in the 6 October 1976 massacre, when Village Scouts and Red Gaur joined with some military and police to massacre at least 46 students protesting at Thammasat University. That evening, the military seized power and installed hard-line royalist Tanin Kraivixien as premier.
