Here's a look at the process that the government followed in the Ajmal Kasab's hanging, which was kept under wraps.
While Pranab Mukherjee rejected the mercy petition on November 8, informal discussions had already been held before that in anticipation of the President rejecting Kasab's mercy petition.
A major calculation was needed to prevent an IC 814 kind of situation where the government would face hostage situation to bargain for Kasab.
The Director of IB, Nehchal Sandhu, was a key official who coordinated between the Centre and state government officials to hang Kasab.
A suggestion was made about burying Kasab at sea like Osama Bin Laden, but was finally rejected in favour of Yerwada Jail.
