Former journalist Santanu Saikia, one of the 13 arrested in the corporate espionage case has alleged that he has been made to sign a blank paper by the police. “I was made to sign a blank paper, don’t know what is happening,” claimed Mr Saikia as police officers took him to court.

Mr Saikia, who runs an energy portal, was arrested by the Delhi Police on Friday for his alleged involvement in leak of classified government documents from the oil ministry. Investigations since the arrests have revealed that documents were also stolen from the coal and power ministries, and included an input for Finance Minister Arun Jaitley’s upcoming budget speech.

Just after his arrest, Mr Saikia had shouted to reporters that he was covering up for a bigger scam. “Quote me, I was doing a cover-up. It’s a Rs 10,000-crore scam,” he said from a moving police van. Earlier today the investigators secured five day custody of one Lokesh Sharma, who the police say, had access to coal ministry documents. According to the police Mr Sharma allegedly procured leaked documents from the coal and power ministers.
