KENT — Police say they arrested about 65 people Sunday night when Kent State University students and other partiers pelted officers with bottles, rocks and debris.

Most are charged with failure to disperse and underage drinking. Those unable to post bond will be arraigned this morning. The others are due in court Wednesday or Thursday morning.

Students on East College Street, just west of campus, began celebrating the end of the school year early Saturday. The party, advertised as College Fest, turned into a riot after police arrested one person. The crowd reacted to the arrest by throwing things at officers, who called for more officers, who were also pelted, Lt. John Altomare said at 3 a.m. in a news release.

A SWAT team and neighboring police departments arrived to help disperse the crowd of "several thousand," Altomare said.Officers marched down the street ordering people to leave. "The crowd continued to throw objects at officers and began building fires in the middle of the street," Altomare said.

When firefighters arrived, they too, were pelted with rocks, bottles and bricks. Police fired tear gas and pepper-spray balls, a dispatcher said.

The crowd was dispersed by 10:30 p.m. Several officers and a firefighter received minor injuries. No one in the crowd reported injuries, police said.
