"One of those cases is before the Equality Court‚" he said.
Mavhidula declined to comment on the identities of those in the other cases.
Limpopo Popcru provincial secretary Nelson Maisela said the alleged incident involving Molepo and Enslin occurred while offices at the police station were under renovation.
He said members‚ who had been told to occupy certain offices by their respective commanders‚ were allegedly ordered by Enslin to vacate the offices.
"Molepo‚ who is a Popcru shop steward‚ went to discus with Enslin where the members were to move to. It was during the discussion‚ which Molepo was having in his capacity as a shop steward‚ that there was an apparent disagreement.
"We have been told - and we have no reason not to believe our shop steward - that Enslin allegedly hurled racial insults at Molepo. There was also apparently a physical scuffle."
Maisela said the incident was reported to Popcru’s provincial secretary‚ Hangwani Mashao‚ who visited the station to establish what had happened.
"The [station] commander‚ however‚ refused to engage with him‚” he said.
Maisela said Mashao reported the incident to the provincial police management‚ who began an internal investigation. But then the waters got muddier.
"We were left in the dark about the findings. We recently established the investigators charged Molepo with misconduct. We tried to engage with police management about the investigation‚ but to no avail."
He said the union was concerned that management was punishing Molepo instead of investigating the allegations against Enslin.
"This is not the first time cases of racism in the province have been swept under the carpet‚ with police management going soft on those behind such behaviour."
He said other cases included the alleged assault of the Modimolle police station commander‚ by an officer from Bela Bela police station‚ and the attack on a Groblersdal police station officer by a fellow colleague.
