Additional Director General of Police (Law and Order) Daljit Chaudhary confirmed the operation was over with the killing of the IS operative.

Chaudhary said, initially it appeared that more than one person was holed up inside the house.

The IG ATS Aseem Arun confirmed that the slain terror suspect was an active member of the ISIS.

"The slain terror suspect belongs to the Khurasan module of the ISIS and was an active member. But, whether he has been indoctrinated or not is a matter of investigation," Arun said.

The ATS wanted the IS operative to catch him alive, but all their efforts went in vain.

Speaking to the media after the anti-terror operation was over, Arun said, "Efforts were made to catch the suspected terrorist (identified as Saifullah) alive, but unfortunately this did not materialise. We fired tear gas shells and chilly bombs, so that he comes out. But, he did not come out."materialise. We fired tear gas shells and chilly bombs, so that he comes out. But, he did not come out."

The ATS commandos then stormed inside the house (after issuing a warning to the terrorist), Arun said, adding "The suspected terrorist then fired at the ATS commandos, which was then appropriately retaliated by the ATS commandos. After this, two rooms were thoroughly searched and checked, and the person identified as Saifullah was found dead."
