The government on Tuesday banned controversial Islamic preacher Zakir Naik's organisation Islamic Research Foundation (IRF) for five years with immediate effect.
The ban has been enforced under the Unlawful Activities (Prevention) Act (UAPA) after approval from the Union Cabinet.
Government is also reported to be in the process of cancelling the FCRA registration of the IRF and a final show cause notice to the organisation has already been issued.
According to a draft note, which is based on the inputs from Maharashtra Police, Naik, who heads the IRF and IRF Educational Trust, has allegedly made many provocative speeches and engaged in terror propaganda.
Maharashtra Police has also registered criminal cases against Naik for his alleged involvement in radicalisation of youths and luring them into terror activities, a source said.
Naik also allegedly transferred IRF's foreign funds to Peace TV for making "objectionable" programmes. Most of the programmes, which were made in India, contained alleged hate speeches of Naik, who had reportedly "urged all Muslims to be terrorists" through Peace TV, sources have claimed.
Naik came under the scanner of the security agencies after Bangladeshi newspaper 'Daily Star' reported that one of the perpetrators of the July 1 terror attack in Dhaka, Rohan Imtiaz, ran propaganda on Facebook last year quoting Naik.
The Islamic orator is banned in the UK and Canada for his hate speech aimed against other religions. He is among 16 banned Islamic scholars in Malaysia.
He had been popular in Bangladesh through his Peace TV, although his preachings often allegedly demean other religions and even other Muslim sects. The Mumbai-based preacher is currently abroad and has not returned to India ever since the controversy erupted.
