Three Makerere University students have so far been hospitalised after police sprayed them with pepper gas.
The injured have been rushed to nearby health facilities for treatment.
One of the victims, Cissy Namata, a third year student of a Bachelor of Arts in Tourism, has collapsed and fainted.
Namata fainted after police hurled expired tear gas canisters at the sixth floor of Mary Stuart Hall.
Male students had raided the all girls’ hall and laid camp.
Here, they stoned police from the balconies and half-open windows.
Police reacted by spraying the hall with pink tear gas which they usually use on opposition politicians.
Defiant, the students threatened to not relent in their cause until the 100% tuition payment before exams is scrapped.
Students told police they want policies that cater for both the rich and poor.
So far, 40 students have been arrested over strike, according to Makerere university security officer, Jackson Mucunguzi.
Mucunguzi said three of them were arrested as they tried to break in the residence of the university VC Prof. John Ddumba.
Students on Wednesday resumed their strike after failing to strike a deal with the university administration on the policy which directs that 100 per cent of their tuition be paid within the first six weeks of the semester.
The University Council has called another crisis meeting to find a quick solution.
Meanwhile, anti-riot police continues battling students who are throwing stones at them in halls of residence.
Police has sieged faculties and crushed students’ barricades in and outside the university.
