In connection with the Chandigarh Grenade attack case, the National Investigation Agency (NIA) has chargesheeted four terror operatives of the Babbar Khalsa International (BKI) terrorist organization. The attack, occurred in September 2024, was intended to target a retired Punjab Police officer, who the assailants believed to be the occupant of the house.

According to officials, the accused include Pakistan-based designated terrorist Harwinder Singh Sandhu alias Rinda, and US-based Harpreet Singh alias Happy Passi. In the chargesheet filed before the Special NIA court, Chandigarh, all four accused persons have been charged under multiple Sections of the Unlawful Activities (Prevention) Act (UAPA), the Explosive Substances Act, and other related provisions for their role in planning and supporting the attack.

The two terrorists — Rinda and Happy Passi — were the primary handlers and conspirators behind the attack, said the statement issued by the NIA. They had provided logistical support, terror funds, weapons and ammunition to India-based on-ground operatives in Chandigarh for executing the grenade attack, it said.

Investigations revealed that Rinda, along with Happy Passi, had orchestrated the conspiracy to strike terror among law enforcement officials and the general public through the attack, as part of the broader aim to promote BKI's terrorist agenda, it added.

They had recruited local operatives, namely Rohan Masih and Vishal Masih, who were tasked with carrying out the attack under their direct instructions, the probe agency said. Rinda and Happy Passi directed the other accused, Rohan and Vishal, to conduct reconnaissance on the target twice before hurling the grenade, investigations revealed, it said.

Investigations in the case are continuing and the NIA is trying to track down other members of the BKI terror group and dismantle its network in India.
