It might be mentioned here that a month before his arrest, in November last year, Katyal had petitioned the Delhi HC seeking stay on any coercive steps by the ED. Interestingly, Katyal in his petition, reviewed by ET, had claimed that he was a protected witness of the Central Bureau of Investigation (CBI). Katyal had claimed that he had "fully cooperated" with the CBI which resulted in a charge sheet filed by the agency. He had also claimed that he was cited as a witness by the CBI in its charge sheet.
