The students, who appealed to the government to intervene or take over the college in Kovaipudur, had come to the collectorate to submit a memorandum seeking basic amenities in the college, police said.
As police refused to allow all the students into the premises, they suddenly grew agitated and tried to surge inside the office of collector Archana Patnaik, they said.
In the melee, three male students were injured and six students, including four girls, swooned, due to heat, they added.
Two students had even attempted to jump off the college building recently, seeking basic faclities like toilets and drinking water.
