Imphal: A 27-year-old militant wanted by the National Investigation Agency (NIA) in connection with a 2021 ambush on an Assam Rifles convoy that killed five people was arrested in Manipur, police said on Sunday.

The “active cadre” of the proscribed People’s Liberation Army (PLA) — Sagolshem Sanatomba Singh, a resident of Tentha village in Thoubal district — was nabbed from Wangbal Maning Leikai during a targeted operation by the Manipur police on Saturday, an officer said.
“Sanatomba is named in a case investigated by the National Investigation Agency (NIA). A mobile phone and two SIM cards were recovered from his possession during the arrest,” a statement issued by the Manipur police control room said.
Commanding officer of 46 Assam Rifles Viplav Tripathi, and his family, along with four Assam Rifles jawans, were killed after their convoy came under heavy attack by militants in Churachandpur district of Manipur on November 13, 2021.
Colonel Tripathi was reportedly returning to his base, accompanied by his wife and six-year-old son, from the Behiang company post when the convoy was ambushed near S Sehken village under Behiang police station, close to the Indo-Myanmar border. At least six jawans—including a havildar, the commanding officer’s driver, and three Quick Reaction Team members—were also injured in the attack.

The NIA had registered a case under multiple sections of the Indian Penal Code, the Unlawful Activities (Prevention) Act, the Arms Act, and the Explosive Substances Act in connection with the incident.
