Prasad was a bomb disposal expert who worked for ATU during Day 1.
After the sting operation involving Pooja Bharadwaj and Bala Ravindran went awry, Jai Singh Rathod recognised that Bala had given Pooja an explosive necklace. He called Prasad up to the suite, and when he arrived he removed the necklace safely from her neck. He explained that it was made of RDX and when detonated would kill anyone in a 10 meter radius.
