Adding a new twist to the face-off between Bengal police and the CBI over the custody of Sandeshkhali strongman Sheikh Shahjahan, the Calcutta High Court today set a new deadline for the Bengal cops to hand him over to the central agency. A bench of Justice Harish Tandon and Justice Hiranmay Bhattacharyya has now asked Bengal police to hand over Shahjahan's custody to CBI by 4.15 pm today.
