More police officers were Monday deployed to Dagoretti High School in Nairobi following a fight between two groups of students at the institution.
Police said at least 11 students were injured when they clashed over a basketball match they were playing.
The incident happened on Sunday evening but boiled over into the night and turned religious.
Then groups used sticks and stones to attack each other in the chaos.
Police said they established that the students were playing basketball in the school when a dispute erupted between two students, Form One and Form Four.
This led to fighting between Sudanese students with Kenyan students.
As a result, 11 Sudanese students sustained minor injuries and were rushed to Garden Medical Clinic in stable condition.
Police said more chaos was reported on Sunday night which now turned religious.
More police were deployed to the area to help quell the violence.
Tension remained high on Monday with more police officers deployed there.
Police said they are managing the issue with more deployments.
