The SABC in a statement on Saturday morning said "the manner in which the coverage of the VBS Mutual Bank story was handled by its newsroom in Polokwane" is now under investigation for possible breaches of its editorial code.
The SABC didn't specify what allegations and evidence led to the internal investigation, or when it would be concluded.
Shocking revelations continue to come to light about the large-scale looting and state capture at the VBS Mutual Bank in a growing scandal that continues to sweep up more politicians and political parties in the disastrous plundering that destroyed the bank through widespread looting schemes.
Last week the report "The Great Bank Heist" was released, compiled by advocate Terry Motau and Werksmans Attorneys, revealing looting of R1.8 billion from VBS Bank.
Last month reports also surfaced about SABC staffers allegedly censored and banned at its Phalaphala FM radio station from discussing the VBS Mutual Bank scandal.
"Should the investigation in Polokwane reveal evidence that the SABC News service's editorial principles of impartiality have been compromised, such violations will be dealt with decisively," says Neo Momodu, SABC spokesperson.
"Any selective coverage - perceived or real - poses a real danger to the editorial character of the SABC News brand and therefore any interference, external or internal in our editorial decision-making will not be tolerated."
The SABC said that it "remains committed to providing the South African public new content that is accurate and balanced, and in a way that is responsible, transparent and unrestrained".
