The clashes took place on Saturday when a group of anarchists gathered in the central Athens neighborhood of Exarcheia to protest the alleged torture of a protester by the police. The incident reportedly took place on September 16 when the protester was arrested.

Anarchists gathered at Alexabdras Avenue and marched in an orderly fashion towards the police headquarters where they claim the torture incident took place. The protesters carried banners and chanted slogans, but as night fell, the demonstration turned violent.
