Two Victorian boys who bashed a schoolmate and left him in a coma could face charges over the attack, which was recorded by other students on their mobile phones, police say.

Investigators said the 15-year-old year 9 student was viciously beaten at Brauer College in Warrnambool on Friday by a pair of fellow students. The footage has possibly been circulated among other students.

Detective Senior Constable Colin Ryan said the suspected attackers, one from year 9 and another from year 7, had been interviewed and could face charges of recklessly causing serious injury and assault in company.

‘‘The two offenders approached the victim. There was pushing, punching and then he got struck to the head and fell down,’’ Detective Senior Constable Ryan said.
