Thirty-seven people were arrested at a Montreal college overnight during an unruly demonstration.
They were taken in by police after protesters erected barricades, with desks, and occupied their school, Cegep du Vieux-Montreal.
The students were protesting tuition-fee hikes planned by the Charest government. Four other people had been arrested at a protest on Thursday.
Police issued an ultimatum shortly after midnight, telling the students to get out or face the consequences.
There had been about 100 people occupying the building.
Some launched objects at police. Other damage was also done to the building.
Of the 37 people subsequently arrested, four were minors. One local radio report quoted a student saying the majority of those arrested did not come from the school.
The school is part of Quebec’s Cegep system, a two-year pre-university network of colleges that prepare high-school students for bachelor’s programs.
Quebec has by far the lowest university tuition in the country and Quebec’s Liberal government wants to nearly double it over five years.
