As secrecy shrouded the hanging of Pakistani terrorist Ajmal Kasab, inmates and authorities of Buxar prison believe that the rope used for the purpose was manufactured by the jail.

Buxar central jail is the sole provider of rope for capital punishment in north and eastern India, its superintendent Surendra Kumar Ambastha said.

"We had supplied a special rope for hanging Afzal Guru to Delhi's Tihar jail on order in 2007," Director, Bihar Prison Department, S B P Singh told PTI.

This rope was, however, not used because of the stay on Guru's execution and might have been used for Kasab, the authorities and inmates of Buxar prison feel.

"Since no requistion had been sent for preparing rope for Kasab, it cannot be said with authenticity if it is the same rope the Buxar jail had supplied to Tihar for Afzal Guru," Singh said. Buxar jail had also provided the rope for the execution of Dhananjoy Chatterjee in Kolkata in 2004, he said.
