The 1986 Killings of Kekuojalie Sachü and Vikhozo Yhoshü refers to the incident of indiscriminate firing by the Nagaland State Police Forces on 20 March 1986 while they participated in a peaceful protest called by the Naga Students' Federation (NSF) to rally against the State Government's decision on the introduction of Indian Police Service (IPS) cadres and the extension of the Disturbed Area Belt from 5 to 20 km along the Indo-Myanmar (Indo-Burma) border.

"The incident was sparked off by the Chief Secretary of Nagaland, I. Longkümer, knowing fully well that the Naga Students' Federation had called a hartal from 6 am to 6 pm, he was on his way to his office in a car when NSF volunteers stopped him.

He was not harassed in any manner nor was his car damaged and a magistrate on duty drove him back to his official residence.

Almost 50,000 Nagas attended the funeral service of Vikhozo Yhoshü and Kekuojalie Sachü at the Kohima Local Ground, which today is the venue of the Martyrs' Memorial Trophy.

His scars always come fresh in front of me.” — Neibano Yhoshü, the mother of Vikhozo recalls (Quote: The Hindu, from 15 October 2015 interview).
