Former Union Minister P Chidambaram left Delhi's Tihar jail today, more than a month after he was taken there, as a court sent the 74-year-old Congress leader to the custody of the Enforcement Directorate in the INX Media money laundering case till October 24. Allowing the probe agency to question Mr Chidambaram in custody, the court also granted him permission to have home cooked food, a separate cell, a western toilet and medicines. The Enforcement Directorate opposed his request for air-conditioning.
