The investigation paper on the death of William Yau Zhen Zhong, six, who went missing before his body was found in Port Klang last month, was sent to the deputy public prosecutor's office for further action.

Selangor CID chief SAC Mohd Adnan Abdullah said, initial police investigations had indicated sudden death.

He said this at a media conference at the Selangor police contingent headquarters here Friday.

On Jan 16, the victim was reported missing in Jalan Putra Mahkota, Putra Heights, Subang Jaya. Eight days later, he was found dead near the jetty in Sungai Sireh, Port Klang.
