More than 1,800 students at the University of Massachusetts at Amherst poured out of buildings and began setting fires, smashing windows, and throwing rocks and cans of beer after the university’s football team lost the Division I-AA football championship to Appalachian State University on Friday night. The state police were called to help university officers quell the two-and-a-half-hour disturbance, according to a university statement, and two officers were treated for bruises after being hit. More than 60 officers in riot gear used pepper spray, smoke, and other tactics to break up the gathering.

The university statement said that 11 people were arrested, 10 of them students. Barbara O’Connor, the university police chief, said the university might seek to identify additional participants by studying security-camera photographs and records of card-entry systems. She said rioters could face both criminal charges and university sanctions.
