The victim was identified as D. Yugendran, 17.

Raub police chief Supt Wan Mohd Zahari Wan Busu said the body was found at 3.15pm, four days after Yugendran’s mother lodged a police report over his disappearance.

This followed the arrest of the victim’s 21-year-old friend last Monday, who had admitted to having struck him with a stick before throwing him into the river, he said.

“The suspect was believed to have been angry with Yugendran who was alleged to have often quarrelled with him.

“In fact, the suspect identified the body based on the victim’s trousers,” he added when contacted here today.

Wan Mohd Zahari said the body was found about 500 metres from where the victim was thrown into the river.

The suspect, who has two criminal records for drug-related offences, has been remanded for four days, beginning Monday, to facilitate investigations.

The body was sent to the Raub Hospital for a post-mortem.
