Police have reportedly arrested the teenage stepsons of Cradle Fund CEO Nazrin Hassan in relation to his death.

According to the New Straits Times today, the two teenagers, believed to be aged 16 and 14, were picked up yesterday evening at the Taman Tun Dr Ismail home of their grandfather.

The two boys are expected to be taken to the Petaling Jaya Magistrate’s Court this morning for a seven-day remand application.

The arrest of the two teenagers was confirmed by Selangor CID chief SAC Fadzil Ahmat, according to Bernama.

As reported by NST, they were arrested after police learned both they and their mother possess archery skills. Nazrin is said to have suffered a puncture wound to his head, possibly from an arrow.

This is the second time the two boys were said to have been arrested, after reports in the Malay Mail and The Malaysian Insight on Thursday.

Quoting sources, the Malay Mail also pointed out that the teenagers were members of their school's archery club.

However, the arrest was initially denied by Selangor police chief Mazlan Mansor.

The NST also said today that police would be applying to extend the remand of  the boys' 43-year-old mother.  

The woman was arrested along with her ex-husband to shed more light on Nazrin's death on June 14.

Initially investigated as sudden death, Nazrin was initially believed to have died from smoke inhalation after a fire broke out in his Mutiara Damansara home.

According to Petaling Jaya police chief Mohd Zani Che Din, the 48-year-old was found dead in his smoke-filled room and had suffered 30 percent burns.

Nazrin's company, Cradle Fund, then issued a statement that he had died from injuries sustained from a mobile phone that exploded as it was being charged.

As the company noted, the postmortem report identified the cause of death as complications resulting from "blast injuries attributable to an exploding handphone that was being charged next to him."

This followed a message from the family that circulated on social media, claiming that Nazrin's phone had overheated and exploded, causing blunt trauma to the back of his head.

In another twist, police then reclassified the case as murder after Fire and Rescue Department investigators found traces of petrol in the deceased's room.

In a press statement published in Malaysiakini on Aug 14, Nazrin's wife had criticised authorities for apparently keeping her and her family in the dark over the progress of their investigations.  

She and her ex-husband were arrested on Sept 4.
