They were returning from the Behiang border post, near the border with Myanmar. He also took his wife Anuja and son Abir in his official vehicle. When the convoy reached Sekhan village of Churachandpur district, the convoy came under a sudden and heavy ambush led by an Improvised explosive device (IED) blast following heavy firings from dense forest, giving soldiers no time to retaliate.
