The migrant worker who allegedly outraged the modesty of the wife of Genji Buskers vocalist Mustam Mustapa was drunk, says police.

This was related by Dang Wangi police chief ACP Zainol Samah who confirmed that a police report was lodged in relation to the case.

Zainol said he was informed by the Sogo Shopping Complex auxiliary police that the suspect - who is believed to be Nepalese - committed the act while drunk in front of the mall at around 9pm, prior to being knocked out flat by the busker.

"Sogo auxiliary police officers and a security guard picked up the man and administered first aid. According to the Sogo auxiliary police, the man who seemed to be a Nepalese was probably drunk - based on the way he spoke and the smell of alcohol on him.

"The injuries he suffered appeared to be only to his nose. After the auxiliary cop gave him a bottle of water to wash his face, the man then got up and walked towards Pertama Complex," he told Malaysiakini .

Enraged with the man who had allegedly outraged his wife's modesty, Mustam took a swing at him during last night's incident, and had apparently knocked him out afterward.

Commenting further, Zainol said the auxiliary police officer did not manage to note down the Nepalese's particulars before he surreptiously left.

He added that the person who lodged the police report also did not inform the Sogo auxiliary police of any further follow-up action, and had only lodged a report on the matter.

Zainol said the incident is being investigated under Section 354 of the Penal Code, for assault with intent to outrage modesty.
