IGP Khalid, who was speaking to reporters at the Bukit Aman Federal Police HQs, said, "We will reclassify the case as murder."
Following his death, Nhaveen's uncle Thiyagarajan had urged police to take immediate action against the suspects
"We urge the police to take immediate action and investigate the case in detail. We want those involved to be arrested and subjected to legal action," he said.
Nhaveen succumbed to his injuries at the Penang Hospital at 5.31pm on Thursday. According to reports, he would be cremated at the Batu Gantung Crematorium at 2pm today.
Yesterday, after the family learned the news of Nhaveen's death, his mother, Shanti, fainted several times. And when she regained consciousness, she was inconsolable.
Shanti, who is a single mother, has lost her only son
Why? Why? Why? Why must this happen to my son?
"What did he do to deserve this? Who am I going to scold? Who am I going to talk to? With whom am I going to share my sadness and happiness?" she was heard wailing in grief.
Nhaveen, who had been declared brain-dead, died without regaining consciousness following his assault on Saturday
He along with his friend Previin was assaulted by a group of five boys.
In the group, there were two of Nhaveen's former classmates, who taunted him.
They called him names, including calling Nhaveen "effeminate".
While Nhaveen pleaded with the two to stop taunting him, they instead called their other friends to the scene and began assaulting both Nhaveen and Previin.
Previin escaped but Nhaveen was dragged to a field and was further assaulted. The group, aged 16 to 20, allegedly sexually assaulted him with a blunt object.
