Police officers have been deployed to monitor the situation and safeguard shoppers, but they have no idea when the protesters would leave.
"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.
The mounting controversy over an H&M ad campaign widely considered to be racist resulted in a South African store being trashed Saturday.
In Menlyn‚ protesters threw clothing around but nothing had been reported stolen. "No arrests have been effected up to so far", Dlamini said.
H&M has closed several stores across Gauteng following the protests. The H&M signage outside the shop had been broken and red fragments were still on the floor.
The image advertising the £7.99 jumper was removed from H&M's U.S. and United Kingdom websites shortly after the outrage broke and the retailer quickly issued a statement apologising to "anyone it may have offended".
General manager of the Menlyn Park shopping centre Olive Ndebele confirmed the skirmishes.
Ndebele said "normal trading" had resumed in the mall. It had to deal with a public relations disaster at the opening of its first SA store‚ at the Cape Town Waterfront‚ in 2015‚ after members of the public queried why there were no pictures of black models in its window. Some held signs that said "H&M say "hello" to coolest monkeys" and "away with H&M racist tendencies".
Some Twitter users had alleged that the EFF had already caused chaos at the Kolonnade Mall. Reports indicated that the H&M shop at Sandton City in Johannesburg had been trashed on Saturday.
The incident comes after the global clothing company H&M came under fire for an advertisement showing a black child in a hoodie that read "Coolest Monkey in the Jungle", sparking worldwide outrage on social media and other platforms.
