Western Cape Democratic Alliance leader Ivan Meyer has opened an incitement case against Cosatu's provincial secretary Tony Ehrenreich over a poster put up in the Cape metro.
The matter was registered at the Barrack Street police station in central Cape Town on Thursday, Meyer said in a statement.
The poster reads: "FEEL IT!!! Western Cape Marikana is here!!!"
Meyer said a National Education, Health and Allied Workers' Union logo was displayed on the poster above a picture of Congress of SA Trade Unions (Cosatu) provincial secretary Tony Ehrenreich.
Text on the poster stated that Ehrenreich "has warned Premier Helen Zille on the imminent Marikana of the Western Cape".
Said Meyer: "Tony Ehrenreich seems intent on creating the climate that led to the violent and tragic clashes between police and workers at Marikana.
"Cosatu is using the symbolism and violence of Marikana to promote its public gatherings. This is happening even as South Africans grieve over... all those who needlessly died in that tragedy."
Police shot dead 34 striking mineworkers and wounded 78 while trying to disperse a group encamped on a hill near Lonmin's platinum mine in Marikana on August 16.
Meyer said Ehrenreich should be punished for this "despicable display of incitement to violence. The DA expects the police to act on this matter without delay."
Cosatu spokesperson Patrick Craven could not immediately be reached for comment.
