Selangor police chief Hussein Omar Khan said three suspects, aged 16, 20, and 51, were arrested to assist in the investigation, including the girl’s boyfriend.

They have been remanded for six days starting today.

Hussein said the cops believed the body was that of 15-year-old Yap Xin Yuan, who failed to return home after a lion dance practice at a basketball court in Batu 11, Cheras, on Dec 19.

Yap’s boyfriend lodged a missing person’s report on Dec 19.

“The body was already decomposed and the victim could not be physically identified. A post-mortem was held at Banting Hospital.

“We need to wait for the results of the DNA tests to confirm the identity of the victim,” Hussein said in a statement.

The case has been classified as murder.

Berita Harian quoted a police source as saying that the victim was believed to have been murdered and thrown into a river.
