Expelled ANC Youth League president Julius Malema was denied entry on Monday to an event where North West miners were to be briefed on developments about their wage demands.
Police stopped Malema at the gates of Wonderkop stadium, where the workers had gathered to be briefed.
After a lengthy discussion, Malema drove off, escorted by about 10 police vans.
It was not immediately clear whether Malema would be able to visit the family of people who were injured by rubber bullets on Saturday, or if he would leave the area.
A police helicopter circled above, while police on foot patrol ran to points of entry to stop Malema if he made any turns.
