Muar police chief Raiz Mukhliz Azman Aziz said the police were informed of an argument between the woman and her 47-year-old son involving sharp weapons at 8.20pm yesterday, Sinar Harian reported.

He said that when police arrived at the house, they found the victim was already dead from wounds on her head and neck.

“The incident was believed to have started after the woman told off the suspect for being noisy. This led to the suspect running amok and repeatedly hitting the victim’s head using a sharp weapon,” Raiz was quoted as saying.

He said the body was sent to the Sultanah Fatimah Specialist Hospital in Muar for an autopsy.

The suspect was arrested on site while the knife and axe believed to have been used in the attack, have been seized.

He said preliminary investigation found the suspect had previously undergone psychiatric treatment and that the case was being investigated under Section 302 of the Penal Code, which is culpable homicide not amounting to murder.
