The campus bars in Cedar Falls, Iowa, closed early, only to be followed by a period of violence and destruction on "The Hill," a student term for the bar area of campus.
Sheriff's officials said 22 people were charged with failure to disperse, a misdemeanor. In addition, two were charged with interfering with an officer.
Almost all of those arrested are believed to be students, according to the sheriff's office.
During the melee, one officers was knocked to the ground when a brick hit him near the ear just below his helmet.
Angie Linn, a UNI student who witnessed the incident, said people were fighting and destroying property for nearly two hours late Saturday night.
Sarah Hawe, a UNI senior, said The Hill was packed and people were pulling out street signs and tearing out parking meters. She said others were throwing whatever objects they could find.
Officers used tear gas and pepper spray to restrain the students.
"It was crazy," Linn said.
Earlier in the day, UNI's football team crushed Illinois State, 47-10.
Ralph Nader, known widely for his role as a consumer activist, will be on November's presidential ballot in Iowa, thanks in part to a group of Iowa State University students.
Citizens for Nader is backing the candidate this November for the presidential ticket.
The Iowa Citizens for Nader committee needed 1,500 signatures to get Nader's name on the Iowa ballot, and obtained 1,800.
Drew Chebuhar, president of the Ames, Iowa, organization, said he was skeptical as to whether the organization would be able to get enough signatures.
Nader will be on the ballot in 21 states, and in 19 states he has official write-in status.
"Nader is concerned about democracy," Chebuhar said. "Nader appeals to young people because he goes to colleges and gets involved."
New Brunswick, N.J., Mayor James Cahill has put his seal of approval on an ordinance requiring party permits for gatherings of more than 50.
Cahill said the application process for this permit would "allow city officials to work more cooperatively with residents to assure events are more successful."
Meanwhile, New Brunswick residents and student organizations at Rutgers University are looking into ways to alter the ordinance.
Critics have called the ordinance "unconstitutional" and have said the ordinance unfairly targets the college community.
Cahill said city officials are "looking to increase compliance with city codes and ordinances, to provide for the safety and well-being of those attending the events and to mitigate the kind of impact that some large parties have had in our neighborhoods."
The ordinance, which Cahill signed last Tuesday, will take effect Oct. 28.
The ordinance will require residents anticipating more than 50 guests to register their events if the hosts also intend to solicit or collect any type of contribution.
Hosts must apply for a $20 permit seven working days before the event.
