PETALING JAYA (THE STAR/ASIA NEWS NETWORK) - The government will not compromise with those who threaten the sensitivities of other races, said Prime Minister Najib Razak.

In a statement on Friday (Sept 18), Mr Najib said the police would investigate those who incited racial hatred at the "red shirt" rally on Sept 16 and those found to be in the wrong would be charged under the Sedition Act.

He said that organisers of the Himpunan Rakyat Bersatu, or United Citizens Gathering, had been granted a permit by the police to gather because they did not have any intention to topple the government. There were also no preparations for any event at the venue, and the organisers had received the consent of the Kuala Lumpur City Hall.

The Bersih 4 rally, however, had been declared illegal as the organisers wanted to topple the government and the protesters were demonstrating at a venue close to where the National Day parade preparations were taking place.

"The rally however went on without any restrictions by the authorities," he said in the statement.

Mr Najib added that the government had come up with the Peaceful Assembly Act 2012 as it was important to give space for the people to speak out.

"If they are not given this space, they would find other ways to voice their opinions," he said.

The " red shirt" rally at Padang Merbok on Wednesday ended peacefully although there was trouble in Petaling Street as protestors clashed with police.
