Muar district police chief Zaharudin Rasip said an investigation showed a 26-year-old woman was confronted by a 25-year-old motorcyclist in the 3.25pm incident.

He said the incident was believed to have stemmed from a misunderstanding between the two parties.

“The suspect was said to have broken the right side mirror of the victim’s car, hit the windscreen and caused damage to the bonnet using his helmet,” he said in a statement today.

A video recording of the incident has been making its rounds on social media.

Zaharudin said the man was also believed to be undergoing treatment for a mental disorder.
