Protesters from the ANC Youth League and other bodies demanded Western Cape premier Helen Zille's presence on Monday to accept a memorandum of demands over service delivery.
They refused to deliver the document to representatives of her office.
Protesters were behaving in a peaceful fashion as leaders of the African National Congress Youth League and its allies addressed them in Cape Town.
Last week, Zille agreed to accept the memorandum on condition ANCYL retracted its statements on making the city "ungovernable".
"We will never apologise to the madam, to Zille. Days of apartheid are over," said ANCYL spokeswoman Magdalene Moonsamy.
