As classes were expected to resume on Tuesday morning, police used stun grenades to disperse a group of students who had gathered near the Wits University’s Great Hall.

Two students including one of the Wits student leaders, Busisiwe Seabe, have been arrested.

Former Cabinet Minister Tokyo Sexwale has urged the students to stop using violence as it will discredit the Fees Must Fall march.

The anti-Apartheid activist and African National Congress ANC stalwart says in 2015, students won the hearts of South Africans who were supporting their campaign as there was no violence and destruction of property.

On Monday, staff were intimidated and ordered to leave the university premises.

Habib has apologised to students affected by a decision to suspend classes last week, saying management is determined to complete the academic year.

Meanwhile, some students say they have been receiving intimidating voice messages such as this one: “We are going to be disrupting the university completely. We want to shut down campus until the fees have fallen completely, so join or get violated.”
