A video has been released that shows the moment a group of protesters stormed a subway station in Sweden and tore down anti-immigration posters that had been put up by a far-right political party.

In the amateur footage, posted to Facebook by Shimin Reshid Mela on 4 August, a large crowd of demonstrators can be seen congregating on the escalators at Ostermalmstorg subway station in central Stockholm, before tearing down the posters.

The slogans, commissioned by the far-right party Sweden Democrats, have stirred outrage in the Nordic country for their supposed racist misconception of Roma gypsies begging in the country.

The poster stated in English: "Sorry about the mess here in Sweden. We have a serious problem with forced begging! International gangs profit from people's desperation. Our government won't do what's needed."

The incident took place after around 1,000 people gathered in downtown Stockholm to protests against the Sweden Democrats.

"Sweden Democrats are involved in spreading racist propaganda. I've never seen this so clearly formulated. It scares me," Amie Bramme-Sey, one of the organisers of the demonstration, told Exponerat.

"It Is a pity that the police cannot cope to protect someone else's property. They let a mob storm a subway station and destroy the property of others," party press officer Henrik Vinge said in a statement. The party also stated that the posters would be put back up on 5 August.

The office of Sweden's chancellor of justice has said it has received more than 50 complaints and will investigate whether the publishers are inciting racial hatred.
