Iranian police have said they are investigating footage allegedly showing a member of their riot squad sexually assaulting a female protester in Tehran after widespread outrage over the video.

The footage, recorded during a protest in the capital's Argentina Square on Wednesday, shows a woman being violently detained and taken towards a motorbike in a street crowded with protesters and riot police. She is surrounded by four armed members of the riot force, and one of them appears to grab her inappropriately from behind. She then slumps to the ground.
