KOTA KINABALU, MALAYSIA: A labourer paid a heavy price for having a six-month love affair with the wife of his colleague in Menggatal near here.

He was killed by his lover's husband and buried in a shallow grave near their living quarters in Kampung Gudong on Friday.

Alson Ali, 34, died after he was viciously beaten up and had his testicles nearly severed by his lover's 40-year-old husband.

Kota Kinabalu City police chief Asst Comm Ahmad Sofi Zakaria said Alson's body was found in a grave about 50m away from the workers' quarters.

He said Alson's family had lodged a police report on Wednesday after he went missing.

Acting on information, he said a police team arrested the suspect at another workers' quarters at Taman Cerah here.

"From our investigations, we learned that the suspect's wife had been having an affair with the victim for about six months prior to the murder," he added.

ACP Sofi said police had recovered the weapons used in the attack and a shovel believed to have been used to dig the grave.
