Former Union Minister P Chidambaram will have to stay in the custody of the Central Bureau of Investigation -- which is questioning him in the INX Media case -- till Thursday, the Supreme Court said today, ordering that "status quo" be maintained in the case. The court had extended his CBI custody for a day yesterday, after Mr Chidambaram's lawyer appealed that the 74-year-old leader not be sent to Tihar jail -- the usual procedure when one does not get bail after police custody expires. Today's extension came after the agency told the court that the senior Congress leader's 15-day custody expires on September 5. "We have made a wrong statement yesterday," the agency admitted.
