The Western Cape Witzenberg municipality is investigating a senior traffic officer for allegedly posting calls for violence against farmers on a social network, The Star reported on Wednesday.
CensorBugbear.org, a news organisation which claims that Afrikaners are victims of genocide, reposted the officer's comments.
They allegedly were, in Afrikaans: "It looks like we must again pick up our AK47s here in the f**king Western Cape. I am sick of farmers and the DA".
The comments continued: "The f**king farmers know who our leaders are, and now our leaders are being targeted," adding that the DA wanted to make the Western Cape a province for "Boere".
The municipality covers Bela Vista, Ceres, Tulbagh and Wolsely.
This comes amid tension in the Ceres fruit-growing area following a series of pay strikes.
Witzenberg municipal manager David Nasson and the SA Local Government Association were investigating a complaint against the officer. He had not been charged and was still on active service.
He could not be reached for comment.
