The Swedish brand received serious flak for this, following which the company released a statement, "We sincerely apologize for offending people with this image".
The protesters were reacting to an ad in which a black child wore a sweatshirt that bore the slogan "coolest monkey in the jungle".
Local media reports said the Economic Freedom Fighters urged shopping malls to evict the Swedish clothing retailer, which has apologised after an outcry in other countries.
Video footage showed activists trashing displays, kicking over and pulling down clothes rails as well as pushing over mannequins.
Bernard Joseph, EFF Western Cape chairperson, said they were protesting against H&M, and were hoping to convince H&M management to refrain from portraying their children as monkeys coming from the jungle."We trust that H&M will listen to our demands", he said.
Floyd Shivambu, an MP from the EFF, tweeted: "That @hm nonsense of a clothing store is now facing consequences for its racism".
"At the East Rand Mall the protesters managed to enter the shop and stole several items".
Police were forced to fire rubber bullets to prevent the scenes escalating.
