A senior Mumbai Police official said security personnel have been deployed outside Naik's 'Islamic Research Foundation' office at Dongri area in South Mumbai, as a precautionary measure in the wake of the recent developments.

"We have neither received any threat perception nor particular instructions from the State or Central government. We have deployed our forces only as a precautionary measure to avoid any untoward incident," the official told PTI.

The Mumbai Police that Zakir Naik's public documents, videos and social media posts will be examined.

The move by the Maharashtra government comes a day after Bangladesh asked India to examine the speeches of Zakir Naik and on the day that another terror attack took place near Dhaka killing four people, including one terrorist.
