Police arrested a mentally challenged Nigerian man after he allegedly submerged a girl’s head in a swimming pool at an apartment in Puchong, Selangor, Malaysia on Saturday.

Other residents and security guards at the apartment became aware of the incident when they heard the victim, a girl aged about eight to 10, screaming for help, NewStraitsTimes reported.

The security guard immediately intervened and stopped the Nigerian man. A video at the pool side has made its round on the social media, believed to be the recording of the situation after the incident.

The Nigerian man clad only in shorts was heard shouting and muttering but the sentences were inaudible. A security guard was seen trying to control the situation.

The video then panned to the playground and then towards a girl clad in pink swimming attire and black pants. A man who was recording the video asked the girl if the Nigerian had choked her, and the girl lifted her lower arm and put it to her neck, saying that “(he) did this.”

Subang Jaya district police chief Assistant Commissioner Mohammad Azlin Sadari said police were notified by the security of the mentally unsound man creating chaos at the apartment’s common area.

“A patrol car was deployed and the man in his 30s was arrested. He was taken to Puchong police station for questioning and later taken to Kuala Lumpur hospital on the same day,” he said.

Azlin said no police report was lodged by the condominium management or the victim.
