A case has been registered by the Mumbai police against an employee of Islamic Research Foundation (IRF) and three others, a senior official said on Tuesday.
Islamic preacher Dr Zakir Naik, who is the founder of the IRF, found himself in a controversy when he was accused of being a source of influence for one of the attackers in the Dhaka terror attack.
Based on a complaint lodged by father of Ashfaque, one of the 21 youths from Kerala who had been reported to be missing and suspected to have joined ISIS, a case was registered against IRF employee Arshid Qureshi, Rizwan Khan and two others, on Monday, at Nagpada police station, the official said.
They have been booked under the Unlawful Activities (Prevention) Act and IPC section 120-B (criminal conspiracy), he said.
Qureshi and Khan were earlier arrested by Kerala police.
In a joint operation by Kerala Police and Maharashtra ATS, Qureshi was nabbed from Navi Mumbai on 21 July for allegedly radicalising youths.
The Kerala police traced Qureshi to Mumbai following a complaint lodged in Kochi by the brother of a young woman, who is suspected to have joined ISIS along with her husband.
Qureshi had been taken to Kerala after a Mumbai court granted his transit remand.
25-year-old Ebin Jacob, brother of Merin alias Mariam who is missing along with her husband Bestin Vincent alias Yahia from Kerala, had told Palarivattom police in Kochi that there was an attempt to forcibly convert him to Islam and make him join ISIS, and that Bestin and Qureshi were behind it.
In a similar operation, Khan, also was allegedly instrumental in recruiting youths to terror outfit ISIS, was apprehended from his residence at Kalyan in neighbouring Thane district on 22 July.
