There were 35 to 40 fires set in student neighborhoods, said Columbus police Sgt. David Howson, whose department arrested about 17 people, five of them on arson charges. A trash bin also was set ablaze, burning two nearby cars, he said.
Battalion Fire Chief Kevin O'Connor said he was treated for bumps and bruises after he and two others were struck by a car that came through a temporary command post set up in the driveway of a student union building.
The two others, an Ohio State official and her husband, were treated early Sunday at Ohio State University Medical Center for minor injuries.
Most students haven't returned to campus because fall classes don't start until Sept. 20, Howson said. Still, police concentrated their patrols on the campus area last night.
"This happens on big games, so we were prepared for it," Howson said.
The victory kept the Buckeyes (2-0) in perfect position for a run to a college football national title. Texas, which saw its 21-game winning streak snapped, is the defending national champion.
