Kuala Langat police chief Akmalrizal Radzi said officers responding to the incident at about 3.30pm found the suspect, a local, armed with a meat cleaver and a rattan stick.

“The suspect acted aggressively and brandished the weapons at police officers and patrol vehicles, posing a threat to both authorities and the public,” he said in a statement.

A video of the incident, showing a man behaving aggressively and threatening a police officer with a weapon at the restaurant, has gone viral.

The man was taken to Tengku Ampuan Rahimah Hospital in Klang for examination.

Akmalrizal urged those with information to contact the nearest police station or the Kuala Langat police headquarters at 03-3187 2222.

The case is being investigated under Sections 353 and 427 of the Penal Code, as well as Section 6(1) of the Corrosive Substances, Explosives and Dangerous Weapons Act.

Section 353 criminalises the use of criminal force to deter a public servant from discharging his or her duty, while Section 427 deals with the commission of mischief leading to damage.

Section 6(1) meanwhile criminalises carrying or possessing an offensive weapon in a public place without lawful authority or purpose.
