Delhi: Former Union Minister P Chidambaram avoided the possibility of being sent to Delhi’s Tihar Jail today as the Supreme Court extended his CBI custody till Thursday. Mr Chidambaram is 74 and should be protected, argued Kapil Sibal for his senior Congress colleague, who has spent 11 days in CBI custody since his arrest on August 21. “There must be some protection to Chidambaram. He is 74 years old. Let him be put under house arrest and not sent to Tihar Jail,” Kapil Sibal appealed to the Supreme Court. If he is sent to judicial custody, then he will be taken to the Tihar, Asia’s largest prison facility. The top court said the former Finance Minister, arrested by the CBI in a corruption case, should apply for regular bail before the competent court. “You can’t humiliate people like this, “Mr Sibal argued, wondering what would happen if the trial court rejected the request and sent him to jail. The court said house arrest was an option only for political prisoners.
