Six rhinos have been killed and three wounded at a farm in Amalia near Schweizer-Reneke, North West, the Hawks said on Saturday.
Captain Paul Ramaloko said the rhinos had their horns removed.
"The carcasses were in the early stage of decomposing. It seems they were killed earlier this week."
The carcasses were found 2km from one another at the Hastrzhoogte farm.
He said no arrests have been made and the Hawks were investigating a case of rhino poaching. – Sapa.
