Police used tear gas and rubber bullets to break up the crowd, estimated at 1,000 people. Rioters started bonfires and hurled chunks of concrete, bottles and rocks at police. The cause of the disturbance was unclear. Many of those arrested are UNC students. They face various charges, including engaging in a riot and second-degree arson.
Students also face disciplinary hearings.
McConnellogue said so far, one student was expelled, one put on probation and others were suspended from school for one semester to two years. Pydyszewski didn't have his hearing. But a roommate said he met Thursday with a lawyer who told him he could face prison time if convicted of arson and engaging in a riot because of an earlier drunken-driving charge. Pydyszewski tossed a couch on a fire, but he didn't hurt anybody or damage anyone else's property, his roommates said Sunday. The number of Colorado teen-agers and young adults seeking treatment for heroin use has more than doubled since 1993, according to state figures.
