On 2 March 1962, Ne Win, with sixteen other senior military officers, staged a coup d'état, arrested U Nu, Sao Shwe Thaik and several others, and declared a socialist state to be run by their "Union Revolutionary Council". Sao Shwe Thaik's son, Sao Mye Thaik, was shot dead in what was generally described as a "bloodless" coup. Thibaw Sawbwa Sao Kya Seng also disappeared mysteriously after being stopped at a checkpoint near Taunggyi.
