Police said the students who had cleared their class 12 exams were frustrated at not getting seats and raised slogans against the college.
The protests soon spun out of control and some of the students set a bus on fire, police said. When the police arrived, the students hurled stones at them.
A police officer said they had to resort to lathicharge to bring the situation under control. The violence continued for nearly half an hour.
The district administration pled helplessness, saying that most graduation colleges have already exhausted their seat quota for the year and cannot admit more students.
Police say some colleges will be given extra security from tomorrow.
