The police have dismissed as untrue social media news alleging that a group of men in red shirts is disrupting public order in the capital city.

Kuala Lumpur Police chief Datuk Tajuddin Md Isa said today the police conducted an investigation and found no trace of such people and no police reports had been made on the matter.

"Police believe the news was circulated to strike fear in the people and to disrupt racial harmony and public order," he said in a statement.

He advised the people against believing the news and called on those who had come across such people to contact the police.

Tajuddin said the police would not hesitate to act against groups which tried to engage in provocation, racism and violation of laws that could undermine public order.
