Kolkata: The Calcutta High Court on Friday ordered a forensic test on the Narada sting tapes. The bench of Chief Justice Manjula Chellur and Justice A Banerjee passed the order while hearing Public Interest Litigations seeking an independent agency probe into the sting which purportedly caught several TMC leaders taking bribe. The entire sting was carried using an iPhone and subsequently transferred to a laptop and then a pen drive. While the iPhone and the pen drive were subsequently handed over by Mathew Samuel to a court appointed special committee, he had refused to part with the laptop contending the committee needed to deposit the cost of the laptop before he can give them the device.-IANS
