1986 Killings of Kekuojalie Sachü and Vikhozo Yhoshü
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 event was so tumultuous that it led three Cabinet Ministers and five State Ministers of Nagaland to resign. Background 
The NSF was observing a peaceful 12 hour protest against the introduction of India Police Service (IPS) in Nagaland and the extension of the 5 km Disturbed Area Belt to 20 km along the international border by the Government of India. Not wanting to confront the police, the students' leaders negotiated with the Magistrate and Police officers on duty. The NSF said, “They arrived of an agreement that the students will move out of the 144 CrPC imposed areas and that the students will be allowed to continue their peaceful hartal.”

Police firing 
As the students were moving out of the MLA Hostel Junction (Phoolbari) as directed by their leader, the Police opened fire on them without any information and warning, killing two and injuring approximately 50 others. In the melee, Vikhozo Yhoshü, 14-year-old student of Kohima English School (Now known as Mezhür Higher Secondary School) and Kekuojalie Sachü, 19-year-old student of Baptist English School (Now known as Baptist High) were shot and killed.

Funeral 
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. Legacy 
“On hearing about my brother being shot, our father decided to go to town with his gun but the villagers stopped him. That was one of the most depressing days — a day I cannot forget in my entire lifetime.”

— Thinuohelie Sachü, the younger brother of Kekuojalie recalls (Quote: The Hindu, from 15 October 2015 interview). “I would dream about my son for nights. One day he appeared in my dream dressed in white and I ran towards him, trying to grab him. But then he disappeared. After that I never saw him in my dreams again. They not only shot my son but smashed all his fingers with rifle butts. My heart aches every time I think or talk of him. His scars always come fresh in front of me.”

— Neibano Yhoshü, the mother of Vikhozo recalls (Quote: The Hindu, from 15 October 2015 interview). NSF Martyrs' Memorial Trophy 
In commemoration of the incident, the NSF Martyrs' Memorial Trophy is held annually.
