The anti-terror investigation agency is also set to summon Naik, who is abroad ever since his name crop up linking terror activities following the Dhaka terror attack on July 1.
Search operations were carried out by the National Investigation Agency at the offices of IRF, premises of Naik as well as that of Harmony Media Pvt Ltd, from where the programmes were being aired on Naik's Peace TV.
"As part of investigation, all actions that need to be taken against a proscribed organisation, including banning of its online activities, are being undertaken," an NIA spokesperson told PTI.
Last week, the central government banned the IRF and declared it as a terrorist organisation under the Unlawful Activities Prevention Act for five years.
If the Islamic preacher fails to respond to the NIA summon, a red corner notice will be issued against Naik through Interpol by it.
The NIA is still trying to block Naik's Facebook page, Twitter account and YouTube videos that contain alleged "objectionable" material and may seek help from authorities in the US where the servers of Internet giants like Google and Yahoo are located, officials.
The NIA had on November 19 carried out searches on 10
premises of the IRF in Mumbai after registering a case against Naik and others under the anti-terror law.
The agency had seized Rs 12 lakh cash and incriminating documents, files as well as electronic storage devices, during searches on various premises, including IRF's head office.
IRF came under the scanner of various security agencies after one of the terrorists involved in the Dhaka cafe attack had allegedly posted on social media that they had been inspired by Naik's speeches.
Justifying the ban imposed on IRF, the government said Naik has been extolling Osama bin Laden, proclaiming that every Muslim should be a terrorist and claiming that if Islam had indeed wanted 80 per cent of Indians would not have remained Hindus.
In a gazette notification, the Home Ministry said the IRF and its members, particularly, founder Naik, has been encouraging and aiding its followers to promote or attempt to promote, on grounds of religion, disharmony or feelings of enmity, hatred or ill-will between different religious communities.
started the process for blocking the URLs of online platforms connected to IRF and Zakir Naik including those on Facebook and YouTube.
It is being done following the due process of the extant statutes, it said.
