The Muar magistrates’ court granted a remand order until next Wednesday against the 32-year-old suspect, who is believed to have mental health issues and tested positive for drugs.

The remand proceedings were carried out at Sultanah Fatimah Specialist Hospital here as the suspect was still undergoing treatment for injuries and mental health observation.

Muar police chief Raiz Mukhliz Azman Aziz said the incident, which occurred at 9.43am on Wednesday in Kampung Tengah, Jalan Bakri, saw the suspect assaulting his 70-year-old father with a cane and a knife before setting the family home on fire.

He said the case was being investigated under Section 436 of the Penal Code for mischief by fire and Section 324 of the Penal Code for voluntarily causing hurt with dangerous weapons.

“The fire also damaged a motorcycle and a car in the incident, with losses estimated at RM150,000,” he said.
