In the case of the attack on Colombo University students in Sri Lanka, the police chased away the students who protested against the police by throwing teargas shells and splashing water.
The student union protested near the University of Colombo, demanding that the local government elections be held as planned.
At that time, the police allegedly barged into the university premises and fired teargas shells at the students and teachers.
In this, some students who were not involved in the protest were said to have been affected, and the police has apologized to the students and professors.
