KENT -- Police from Kent, Kent State University, Portage County Sheriff's Office, Brimfield Police, Metro SWAT and Hudson worked to disperse large crowds of students throwing beer bottles after fights broke out during the annual "College Fest" near the KSU campus early Saturday evening in downtown Kent.
Police say some of the nearly 3,000 students and revelers threw beer bottles at police and continued their unruly behavior.
Police were attired in riot gear and, according to students who tweeted from the scene and the website kentwired.com, using tear gas and "flash-bang" devices to disperse the crowd.
Twitter was flooded with tweets with the hashtag CollegeFest.
The Kent Fire Department was sent to University Drive after a couch was set on fire near the roadway.
Emily Vincent, the director of KSU media relations, said that Kent State "is closely monitoring today's events and supports the city in its efforts to keep celebrations safe for everyone involved."
Vincent said the problems were not occuring on the campus but near College Avenue in downtown Kent.
Police tell Channel 3 that at least 30 people have been arrested as of Sunday morning. People continue to be processed and booked in.
To deal with all the cases, court hearings are being spread throughout the week. Crews were out Sunday morning cleaning up the aftermath of what some are calling a "riot."
