Dr. Naik, in a video response after the deadly Dhaka cafe attack, had said that he was not surprised that one of the gunmen knew him since he "inspires millions across the world". Amid demands from various leaders of his arrest, Mumbai Police is still looking for a reason that can allow them to take him under custody.
Meanwhile in India, following the Centre's tough stand on Zakir Naik's controversial comments on terrorism, nine teams from the National Intelligence Agency (NIA), the Intelligence Bureau (IB) and other agencies are scanning his activities, while special teams are scanning every footage of his speeches.
Earlier on Thursday, Union Minister for Information & Broadcasting M. Venkaiah Naidu indicated that Naik could face action if his preachings and teachings were found to be objectionable.
Naik has denied the claims, arguing that even if the attackers watched his sermons it did not mean they were adapting his teachings. The report said that one of the terrorists had propagated on Facebook past year quoting Peace TV's preacher Zakir Naik urging all Muslims to be "terrorists".
The cabinet committee on law and order on Sunday made a decision to ban transmission of Peace TV that broadcasts speeches by Mumbai-based Islamic scholar Zakir Naik.
Doctor-turned Naik's speeches are believed to have inspired some of the Bangladeshi militants, who killed 22 people, mostly foreigners, at an upscale restaurant in Dhaka on July 1. "The Home Ministry will study (his speeches)".
Naik, who is based in Mumbai, said from Makkah that he "totally disagreed" that he had inspired the terror attack in Dhaka.
However, in another tweet, he said: "I appeal to all people worldwide to work together on the causes, ways and solutions to eliminate TERRORISM FROM OUR MIDST".
Young militant Rohan Imtiaz, son of an Awami League leader, posted a message on Facebook a year ago quoting Peace TV's preacher Naik "urging all Muslims to be terrorists".
Talking to reporters on the sidelines of an event here, the Home Minister said Naik's speeches were being examined and "whatever is justified will be done".
Official sources said the Home Ministry has ordered investigation into alleged diversion of funds by Naik and his NGO Islamic Research Foundation (IRF).
