Police said they are investigating the motive and conspiracy behind the incident and plan to cross-examine all the accused to unravel the plot. All six were using 'Signal' chat app to avoid any suspicion and Karnataka-based Manoranjan D is believed to have motivated the other suspects to participate in the act. He used to frequently travel to New Delhi and Bengaluru for meetings. He was the one who recced Parliament twice -- first during the monsoon session and then the special session of Parliament in September, police said.
