The Special Task Force of Assam Police entered a rented house in Guwahati’s Satgaon area, seizing a mobile phone, an array of SIM cards and documents the department described as incriminating.
The raid followed a preliminary tip from Gajraj MI, Tezpur, which IGP Partha Sarathi Mahanta relayed to Senior Superintendent Barun Purkayastha for verification and action.
Singh, a 31‑year‑old resident of Purba Champaran, is alleged to have passed classified information about security forces to a Pakistan intelligence operative, according to police.
The seizing of the phone and documents is said to reveal links between Singh and the foreign agency, prompting a fresh counter‑espionage probe in the state.
Local residents in Satgaon have reported a spike in police presence and a temporary curfew, reflecting heightened security concerns.
Police will charge Singh under the National Security Act, and a court hearing is scheduled for next week.
