The police department's weekend report says 12 of the people were students and one was an alumnus. East Lansing police say there were at least 57 fires, many in a neighborhood of apartments just off the eastern edge of campus.
The Lansing State Journal posted video online showing thousands of revelers cheering loudly as a couch was tossed on a fire. The street scenes early Sunday occurred after the Spartans defeated the Buckeyes 34-24 in Indianapolis and earned a Rose Bowl bid.
Police are offering up to $20,000 for information that leads to convictions.
Some 75 miles away in Ypsilanti, police reported two couch fires related to the game.
Michigan State basketball coach Tom Izzo said he's disgusted and disappointed by what happened. MSU president Lou Anna Simon also called the behavior disappointing.
