Perak police chief Mior Faridalathrash Wahid said the students, a 15-year-old and three aged 13, were held after they gave their statements at the Kuala Kangsar police district headquarters today.

This brings the total arrests to 10 so far, after six students were taken into custody yesterday.

“Six of them were released this evening while four more will be released tomorrow after the investigation is completed,” Mior said.

A group of teenagers believed to be boarding school students were seen punching and kicking a student in several video clips lasting between 13 to 30 seconds.

The videos went viral on social media and the incident was heavily criticised by netizens.

An initial investigation found that the incident occurred between 1am and 2am on Dec 9 and involved a 13-year-old victim.
