The Police and Prisons' Civil Rights Union (Popcru) in the Waterberg district of Limpopo has declared a dispute with management over "racist behaviour".
The claim over racism, made at the Mookgophong police station [formerly Naboomspruit], surfaced after an administration officer said she was locked out of her office by a white colleague.
She said the colleague claimed "she stank" and should not be allowed to share the same office space with her.
The colleague would lock the office when she was alone inside and refuse entry to the administration officer, Sowetan was told.
The complainant, whose name is known to Sowetan, reported the matter to her superiors but according to her they have failed to resolve the matter.
The complainant is also secretary of the police union in Mookgophong.
Hannes Mashilo, Popcru's shop steward in the Waterberg district, confirmed this week that the union had declared a dispute with management at the station.
"There is no way relations between the two can be smooth as long as they continue treating each other along racial lines," Mashilo said yesterday.
He said: "We want punitive measures to be taken against the perpetrator because there is no room for racism, especially not in the police service."
Mashilo also claimed that the complainant was barred from using the same toilet as her white colleagues.
She was forced to use toilets situated further away and used by officials who sympathise with her predicament.
Mookgophong station commissioner Senior Superintendent Marubini Munyai told Sowetan the matter was being investigated.
"We are currently in discussions with Popcru's provincial office to come up with solutions to the matter," he said.
