Chandigarh, Aug. 30 -- The special National Investigation Agency (NIA) court on Friday issued an open non-bailable warrant against another accused in the Sector-10 hand grenade blast case reported last year. The warrant was issued against Shamsher Singh, alias Shera, alias Honey, after the prosecution moved an application on his behalf. While passing the order, the court of judge Alka Malik stated, "There is sufficient evidence on record to substantiate active involvement of accused Shamsher Singh in the conspiracy of crime in question. Since, he is not responding to the notices and is not available at the given addresses of India, this request of the prosecution is allowed. Let an open dated non-bailable warrant against accused Shamsher Singh be issued." Police said US-based Harpreet Singh, alias Happy Passia, along with Pakistan-based terrorist Harwinder Singh, alias Rinda, as well as Shamsher Singh, are the absconders in the case. Passia and Rinda have already been chargesheeted by the NIA. Currently, there are three accused in custody including Rohan Masih, Vishal Masih and Abhijot Singh. The prosecution moved an application for issuance of open dated non bailable warrant urging that during investigation sufficient material has emerged to substantiate involvement of accused Shamsher in the instant conspiracy. The prosecution also stated that Shamsher is a close associate of co-accused Passia, who is involved in recruiting youth to collect weapons sent through cross border smuggling, conduct recces of targets and carry out firing on them. In the order, the court stated that the disclosure statement of accused Abhijot detailing the role of Shamsher was seen and signed. Notice sent under Section 35 (3) of BNSS, 2023 seen and signed. The attack was masterminded by ISI-backed Pakistan-based terrorist Harwinder Singh, alias Rinda, of Babbar Khalsa International (BKI), and USA-based Passia.
