Iowa State University's president has halted a popular annual celebration after a rowdy crowd caused damage near the school that hurt one student and led to the arrest of two people.

University President Steven Leath said at a news conference that Veishea, an annual multi-day celebration on campus, would be canceled after 5 p.m. Wednesday. Officials have not decided whether to hold it again in future years.

The university says one student was seriously injured after a crowd disturbance near the campus late Tuesday, in which people overturned cars and threw rocks at officers. Police Cmdr. Geoff Huff says people knocked down two light poles, striking the student who was badly hurt. The school has not identified the student.

Police told The Associated Press that the crowd dispersed early Wednesday.
