South African police arrest student protest leader

South African police have arrested a leader of university student protests for free education that have swept many campuses since last month, forcing some to suspend classes.
The student council of the University of the Witwatersrand in Johannesburg said on Twitter that police detained Mcebo Dlamini, a former council president, in his room at a student residence early today.
Dali Mpofu, a lawyer who has assisted student protesters, said he spent an hour with Dlamini at a police station after his arrest.
South African police say they arrested a man at the university at 1 AM today during investigations into "violence, criminality, intimidation."

The police have not identified the suspect.
Students and police have clashed at the university and in surrounding streets in the past week.
