The appellant Yeasin Sk was convicted by the trial court for the rape and murder of an approximately 11-year-old girl on 1 February 2009, who was found hanging in a mango orchard, half-clad and bleeding, with a red Hero bicycle nearby. The Calcutta High Court examined whether the conviction under Sections 376 and 302 IPC was sustainable, particularly in light of key witnesses PW-3 and PW-5 turning hostile and retracting their earlier statements. The court held that the retractions were not credible, as the witnesses could not articulate specific threats, and their prior statements—including a Section 164 CrPC statement made on oath—were treated as substantive evidence corroborated by other prosecution witnesses. The last-seen theory was established through multiple witnesses who confirmed the appellant took the victim on his red ladies' bicycle, which was recovered from the scene, and the appellant offered no alibi under Section 313 CrPC, warranting an adverse inference. The court upheld the conviction, distinguished the appellant's case from the acquitted co-accused Royal Sheikh, and directed the State to pay Rs. 4,00,000 as compensation to the victim's family under Section 357A CrPC.
