Kasab was informed about hanging on November 12, govt sources said.

According to official sources, a senior jail official read out the death warrant to Kasab at his cell and also informed him that his clemency petition had been rejected by President Pranab Mukherjee.

After reading out his death warrant, Ajmal Kasab, who was part of the 10-member Lashkar group that carried out the dastardly attack on November 26, 2008, was asked to sign it which he did, the sources said.

Later, he was taken by the Yerwada Jail police and the local police was kept out of the loop to maintain secrecy of the operation.

Barring a couple of officers, the 200-strong contingent of ITBP, which has been guarding him since March 2009, had been kept out of loop about his transfer to Pune jail.
