ANN ARBOR, MI - A motorcyclist was struck by a falling tree on the University of Michigan campus on the afternoon of Sunday, April 16.

Authorities were called about 4:30 p.m. to the incident in the area of 2300 Hayward Avenue on the University of Michigan's North Campus, a university police official confirmed. The location is on the crosswalk in front of the Herbert H. Dow building.

The motorcyclist, a 22-year-old student, was hospitalized in serious condition, said Diane Brown, spokeswoman for the University of Michigan Division of Public Safety and Security.

Though the matter remains under investigation, Brown said it's believed wind and the saturation of the ground may have caused the tree to fall.

The motorcycle remained standing underneath branches of the tree about 5:15 p.m. Sunday.

Further details on the incident were not immediately available.
