In this April 20, 2012 photo, a demonstrator is taken away from the Montreal Convention Centreas students demonstrate against hikes to university and college tuition fees in Montreal. Police in Canada say 85 people have been arrested after thousands of students angry over tuition increases smashed windows in Montreal in a latest round of protests. The rioting came after talks broke off Wednesday, April 25, 2012, between the Quebec provincial government and student groups over the planned tuition increase of $375 a year. The talks broke off after the government ejected the most militant student group from the discussions. (AP Photo/The Canadian Press, Paul Chiasson)
