New Delhi, Sep 15 (ANI): The Supreme Court on Monday directed lawyer Prashant Bhushan to disclose the source of his information in the 2G scam case about CBI Chief Ranjit Sinha. The court asked Bhushan to submit the name and address of the whistle-blower in a sealed envelope. The CBI chief, defending himself, has said that 90 per cent of entries in the register are forged while some entries may be genuine. However, Bhushan said that this infringes on the privacy of the whistle-blower and therefore needs permission from the same. The court thus gave a week's time to Bhushan and the next hearing is to take place next Monday.
