A thug punched an innocent woman in a shocking attack on the street after jumping out as she walked by.
The violent random assault was filmed by another man, who can be heard hooting with laughter as the woman hit the floor.
The footage is believed to have been filmed in Malmo, Sweden and although it is not known when it was filmed, it was shared on social media at the weekend.
The woman doesn't appear to know her attacker and does not interact with him in the moments before he hits her.
As she walks towards the camera, the thug steps into shot and thumps her in the head.
She falls to the ground and hits the pavement, before falling between two parked cars.
The woman appears to have been knocked out briefly before she starts to sit up holding her head where she was hit.
The thug then runs off and the man filming, who seems to be known to the the attacker, continues filming and laughs loudly.
Official details have not been released by Malmo Police, although the unconfirmed reports in the country's media say he is a 20-year-old man.
No arrests have been made.
