Patiala, May 3 -- In a major breakthrough in the Shambhu railway track blast case, Punjab Police on Saturday established that the same terror module was behind multiple recent attacks in the state, including the Sirhind railway track blast on January 23, 2026, and the grenade attack on the CIA office in Moga on January 7, 2025. Punjab director general of police (DGP) Gaurav Yadav said this came to light following the arrest of Gurjinder Singh, alias Baba Beant-an accomplice of Jagroop Singh-on Saturday. Gurjinder was apprehended in a joint operation by teams of the state special operations cell (SSOC) Amritsar, Patiala police, and counter-intelligence, Pathankot. The DGP said Gurjinder Singh and Jagroop Singh carried out the Shambhu railway track blast on April 27. Jagroop was killed in the botched attempted detonation. "The ongoing investigation has revealed that Gurjinder Singh and Jagroop Singh carried out the Shambhu train blast. It has been technically verified," said Yadav. He said the same module was responsible for the Sirhind railway track blast on January 23 this year and the grenade attack on the Crime Investigation Agency (CIA) office in Moga on November 7 last year. The Sirhind blast involved an explosion on the railway track that damaged a portion of the line and disrupted train movement, though no casualties were reported. "The interrogation of Gurjinder Singh and digital footprints have revealed that the Sirhind train blast and the grenade attack on the CIA Moga were also carried out by both of them," the DGP said. Following the Shambhu incident, Punjab Police uncovered a Pakistan-linked terror module and arrested four individuals in connection with the failed sabotage attempt on the Rajpura-Shambhu railway line. Yadav said the attackswere carried out under the directions of foreign-based handlers, pointing towards a coordinated terror conspiracy. The DGP said Gurjinder and Jagroop were long-time associates and on the day of the Shambhu blast, the duo travelled to Rajpura separately to avoid detection. Gurjinder was present at the scene when the blast occurred, but managed to escape unhurt as he was standing at a distance, he said, while adding that Gurjinder fled the spot only after realising that Jagroop had died in the premature detonation. Patiala senior superintendent of police (SSP) Varun Sharma further disclosed that to evade detection, the module maintained strict radio silence and took extensive precautions during their movements. Further investigations are ongoing to trace other members and handlers linked to the module, he added....
