PETALING JAYA: A massive operation to identify and nab Zayn Rayyan Abdul Matiin's killer has been underway around the Idaman Apartment area since last night.
This morning, more investigators and officers believed to be from the Forensics Unit as well as IPK Selangor and Bukit Aman Criminal Investigation Department gathered at the scene where the boy's remains were found on Wednesday night.
Officers and personnel were seen combing the site again for any possible clues or signs which could help in the ongoing investigation.
The search has been expanded from the initial scene to along the waterway.
The investigative team is also expected to conduct door to door checks later.
Yesterday, Selangor police chief Datuk Hussein Omar confirmed that the boy who went missing on Tuesday had been murdered.
His body was found about 200 metres from where he was last seen at 9.30pm Wednesday.
