Nine people will appear in the Bellville Magistrate's court on Thursday for dumping human waste in the departure terminal at Cape Town International Airport.
Lt-Col Andre Traut says they've been charged under the National Key Points Act, as the airport is a key point.
Two of the men arrested have been identified as ANC members already facing ANC disciplinary action for a similar offence.
One of the men said they'd taken their protest to the airport to send a message to the United Nations that his people have been living with uncleaned toilets that are filled up for three months.
ANC provincial spokesman Phillip Dexter said such behaviour was unacceptable and that the party condemned it without reservation.
