'At the moment we are only treating them as suspects,' a police officer said.

Transport Minister Sibusison Ndebele has condemned the shooting.

He said the government remains committed to implementing the BRT system in partnership with all stakeholders, including the taxi operators, through the National Joint Working Group (NJWG).

The South African National Taxi Council (SANTACO) has denied any involvement in the attack.

'Yesterday's (Tuesday) incident does not reflect our position of constructive engagement to resolve the differences,' SANTACO said in a statement.
