A day after the five accused in the Parliament security breach were brought back to Delhi following their polygraph, narco-analysis and brain mapping tests, a police source claimed that Manoranjan D was the mastermind behind the incident. Earlier, the police had said that Lalit Jha was the mastermind behind the December 13 incident.

All six accused -- Sagar Sharma, Manoranjan D, Amol Shinde, Neelam Azad, Lalit Jha and Mahesh Kumawat -- were presented before the Patiala House court on Saturday which sent them to judicial custody, police officials said.
