Khan has been lodged in the egg-shaped cell as he claimed to be facing threat to his life from Kolkata businessman Kashinath Tapuria, a co-accused arrested in the money laundering case, jail sources said today.
"Assessing the seriousness of the threat Khan is facing, he was put in this special cell. Khan is not being allowed to mingle with other inmates and, as per the court orders, he is getting home made food," Inspector General (Prisons) Surinder Kumar said.
Khan was arrested by Enforcement Directorate on March 17 after the Supreme Court cancelled his bail granted by a Mumbai court. For seven days, Khan was in the ED''s custody and then shifted to Arthur Road jail.
After he was remanded in judicial custody in the last week of March, Khan had claimed he was receiving threats from Tapuria.
"Khan is facing serious criminal charges and we do not want to take any risk," Kumar said.
On March 29, the Supreme Court had directed the Union and the Maharashtra governments to provide adequate protection to Khan and his family.
With several hardcore criminals and gangsters lodged in the Arthur Road jail, Khan was not being allowed to mingle with anybody, said another official on condition of anonymity.
"After Kasab's security, Khan's protection is our priority," he said.
Last July, notorious underworld don Abu Salem, extradited from Portugal five years ago to face trial, was injured in an attack by Mustafa Dossa, a close aide of fugitive ganglord Dawood Ibrahim, inside the jail.
After the assault, Salem was shifted to the Taloja Jail in Navi Mumbai, while Dossa was moved to the Thane Central Prison.
Last September, Salem's aide Mohammed Mehndi Hassan, an accused in the 1995 murder of builder Pradeep Jain, suffered injuries in an attack in the jail.
