India 'to examine' request to ban Islamic preacher

India has said it would examine if Bangladesh makes any request to ban a controversial Indian Islamic preacher who was followed by one of the five Bangladeshi youths involved in the killing of 22 people at Holey Artisan Bakery in Dhaka last Friday.

"We don't ban individuals. We ban organisations. So far, there is no formal communication from Bangladesh. If they request us, we will examine what can be done," Minister of State for Home Kiren Rijiju told reporters.

According to a Bangladesh newspaper, militant Rohan Imtiaz, son of an Awami League leader, propagated on Facebook last year quoting the controversial Indian Islamic preacher Zakir Naik.

Naik, in his lecture in Peace TV, reportedly "urged all Muslims to be terrorists".

Naik, a popular but controversial Islamic orator and founder of Mumbai-based Islamic Research Foundation, is banned in UK and Canada for his hate speech aimed against other religions.

He is among 16 banned Islamic scholars in Malaysia. Another Dhaka attacker Nibras Islam, used to follow two alleged suspected recruiters of Islamic State - Anjem Choudary and Shami Witness - on Twitter in 2014.

Meanwhile, BJP ally Shiv Sena today sought action against the controversial Indian Islamic preacher Dr Zakir Naik.

Sena lawmaker Arvind Sawant said he had written to the Indian Home Minister seeking a ban on Naik and his organisation, the Islamic Research Foundation, in the country's interest.

"People whose language propagates violence against nation's unity should be banned," Sawant said in the letter.

"Islam teaches love and peace. But everyday is a day of high alert now. I appeal to the Home Minister that action needs to be taken," he said.

"How do young children in our country join ISIS? So maybe we are failing somewhere....we should know the seriousness of this situation.  Radicalised minds can now take any step. In the name of Islam, they are slaughtering people who cannot recite verses," Sawant said.
