Ampang Jaya police chief Azam Ismail said the victim, a cook, was awakened at 6.30am by the sound of the bathroom door being slammed.

The 52-year-old retaliated by slamming the bathroom door in response.

The suspect then emerged from his room holding a metal rod, believed to be part of a guitar stand. A heated argument ensued, following which he allegedly struck the cook.

The musician also threatened to call his friends over to beat up his housemate.

The cook, who suffered injuries to his hands, lodged a police report on June 30.

Police arrested the musician on July 2 and seized a black guitar stand.

“He was released on police bail after giving his statement,” Azam said in a statement.

He said the housemates had quarrelled before, when the musician refused to turn down the volume of his music despite repeated complaints.

Police are investigating the case for voluntarily causing hurt and criminal intimidation.
