Two students from the University of Johannesburg UJ Soweto campus are still at large following the murder of a learner.
Two other students were arrested yesterday and will appear in court soon.
On Tuesday, the students who had been drinking allegedly stopped a school bus and demanded that the driver take them to buy more alcohol.
However, the learners protested as they wanted to go home.
One of them, an 18-year-old, was reportedly beaten with a baseball bat and his throat was slit.
