Naikoo was born in Beighpora, a village in Awantipora tehsil, Pulwama district, in April 1985. Some of his relatives have said that he had a passion for painting, especially roses, during his school and college days. After earning a degree in mathematics he became a math teacher at a nearby school. He gave free tuition to children from economically weaker backgrounds. During the 2010 unrest, he was put under detention by the security forces. On 1 June 2012 he disappeared and resurfaced with a gun. In the next five years he lived the life of a militant and rose to become the Hizb-ul-Mujahideen commander in Jammu and Kashmirafter the death of Burhan Wani and the defection of Zakir Musa. In March 2014, he was involved in killing of a Sarpanch’s father Haji Ghulam Mohd Dar in Dogripora. He was also wanted for killing and abduction of police officers, murder, firing on a police bus, looting and terror requirement among other crimes. In 2018, police detained Naikoo's 70-year-old father. In retaliation, family members of police were kidnapped by militants from across south Kashmir. His father was soon released and the 11 hostages were accordingly let go by Naikoo. Jammu and Kashmir Police had alleged that he would "loot orchard owners". Naikoo started the practice of offering gun salutes to militants killed in encounters and posting them on social media. He was responsible for recruiting "scores of young Kashmiris in an armed quest for independence from India". Police say he rarely used mobiles, used a VPN when he had to, and was known to have used the Bat Messenger app to communicate. Naikoo's videos were circulated on the social media; one such video after the revocation of the special status of Jammu and Kashmir showed him saying that the revocation was "irrelevant to us" and the fight would continue. Naikoo’s last audio message in April was related to the COVID-19 pandemic where he requested people to follow medical advice to keep themselves protected.
Death
Naikoo was killed in a gun battle with 21 Rashtriya Rifles and Jammu and Kashmir Police on 6 May 2020 in Beighpora. He was with an associate who was also killed. He did not prove to be a great fighter. The encounter was viewed as a big victory for the security forces.Naikoo had been a category A++ terrorist and was in the top 10 on the most-wanted list in Kashmir. As per policy Naikoo's body was not handed back to his family. He was one of Kashmir's longest surviving militants. As a precautionary measure to curb the spread of news, government authorities information imposed communications and information blackouts by barring internet and mobile services across Kashmir valley right after Naikoo's assassination. Protests against the killing of Naikoo were the first since August 2019, when the revocation of Kashmir's special status took place, with at least one protester dying and 50 seriously injured with bullet wounds to the chest and some with pellet injuries in one or both eyes. Syed Salahuddin, the head of Hizb-ul-Mujahideen, who is designated as a terrorist by India and the United States, said that "the sacrifice would help them achieve the mission that they had set out to achieve". On 10 May 2020 Saifullah, also known as Gazi Haider, replaced Riyaz Naikoo as the new operations commander.
