SS Yadav, former Chandigarh DGP, unexpectedly joined the Border Security Force (BSF) as DIG. His appointment, initially mistaken as an April Fool's prank, is considered unprecedented. Yadav will undergo familiarization training before receiving a formal posting. This move follows a new rule allowing state DIGs to be appointed as central DIGs, despite Yadav's junior colleagues holding higher BSF ranks.
