Malaysian Prime Minister Mahathir Mohamad said on Friday that the country will revoke the Permanent Resident (PR) status of Islamic preacher Dr Zakir Niak if investigations show that his actions are causing harm to the country's well-being.

Mahathir said that the government is currently waiting for the result of the investigation whether the leader's alleged "inflammatory remarks" against minorities residing in the country, reported local media MalayMail.

"He (Zakir) has PR status. We can take away the PR status if he does something that is detrimental to the well-being of the nation," Mahathir said.

"At this moment the police are investigating if he is doing that or not. If he is doing it, then it is necessary for us to take away his PR status," he added.

The Malaysian prime minister also said that there was a need to take action to prevent Naik from making provocative speeches, which could lead to communal tension in the country.

When asked whether he will demand a public apology from Naik, he said, "At this moment, leave it to the police to investigate on the seriousness of the statements that he had made."

The controversial preacher was reportedly barred by Malaysian authorities from addressing an Islamic event from August 16-18, following his allegedly "racist remarks" last week.

Naik has been living in Malaysia for approximately three years after he was granted permanent residence. However, he has found himself in the centre of a controversy after some videos of an event emerged. At the event, he said Malaysian Hindus are more loyal to Indian Prime Minister Narendra Modi.

Meanwhile, the federal police authorities are currently investigating the Islamic preacher for intentional insult with intent to provoke a "breach of peace" after 115 complaints against is latest remarks during a lecture at Kota Baru, Kelantan.
