COLUMBUS, Ohio (AP) --Some students took an early plunge into a frigid Mirror Lake on the Ohio State campus to defy the university's attempt to regulate the traditional jump.

The jump, a tradition during "Beat Michigan Week" attracts thousands of people, and the university previously allowed it. But this year, officials erected temporary fencing around Mirror Lake and said only students issued special wrist bands could take the plunge Tuesday.

A crowd of students and other fans stormed the fence Monday night to make the jump. A Franklin County sheriff's deputy says authorities decided to remove blockades after people knocked down some of the fence and ran through caution tape.

OSU had said the restrictions were meant to protect students, who organized the preemptive jump on social media.
