Parliament attack convict Afzal Guru, who was hanged on Saturday morning at Tihar Jail, was buried inside the prison complex soon after his execution.
"He (Guru) was buried near jail number three," said a top Tihar Jail official.
Guru spent over 10 years on death row in Tihar Jail. He was hanged at 8 am in an operation shrouded in secrecy.
The mercy plea of 43-year-old Guru, who was sentenced to death in 2002 by a special court, was rejected by President Pranab Mukherjee a few days ago, Rashtrapati Bhavan spokesperson Venu Rajamony said.
The body of Guru was buried in Tihar Jail as was done in the case of Pakistani terrorist Ajmal Kasab, who was buried in Pune's Yerwada jail soon after his execution.
Union Home Secretary R K Singh said President Pranab Mukherjee had rejected the mercy petition of Afzal Guru on February 3.
