Both men have been charged under various provisions of the Unlawful Activities (Prevention) Act, Explosive Substances Act, Arms Act, and Bharatiya Nyaya Sanhita, an official statement said.

The grenade attack on Sandhu's house in Raipur Rasoolpur village in Jalandhar district was carried out in the early hours of March 16, 2025.
