The injured have been admitted to a district hospital and condition of five of them was serious, said Bikramananda Moharana, chief district medical officer, Keonjhar.
Following the incident, irate students went on a rampage in the college campus and allegedly assaulted the supervisor of the construction company Biranchi Swain, police said.
The students did not spare the college staff either, who had locked the supervisor inside the staff common room to protect him, as they broke open the door and manhandled them along with Swain, police said.
Police force led by Keonjhar SDPO Maheswar Sethi and local inspector-in-charge Satyajit Das rushed to the spot and brought the situation under control.
The students alleged that the wall collapsed due to poor quality of work and inferior material used in the construction.
