Though 20 persons were arrested in the case, the CID filed the chargesheet against 11 of them, as there was insufficient evidence against the remaining nine, an official said. “Accordingly, the evidence collected during the investigation is presently insufficient to constitute a prima facie case warranting their prosecution,” the CID-CB explained in a statement. It was alleged that a mob tied the GRP constable Soumya Ranjan Swain to a pole and assaulted him, leading to his death. It was alleged that Swain assaulted the women and attempted to rape one of them, triggering an attack by an enraged crowd. While one case was related to the murder of the GRP constable, and another concerned the alleged attempt to rape the woman.
