The incident led to the hospitalisation of 46 students on Tuesday.
More than 300 students who arrived in the Enga capital of Wabag on Wednesday night in three hired buses said students from Enga, Hela, Jiwaka, WHP and SHP were attacked without any good reason by their Eastern Highlands and Chimbu colleagues.
The students said the attackers were allegedly assisted by locals with dangerous weapons, including fire-arms, bush knives, spears and arrows.
