The European court ruled Tuesday there was a violation of human rights in a case involving a Turkish woman attacked by police in Istanbul.
The court said videotape evidence of a March 6, 2006, demonstration in Istanbul showed police officers beating protesters with batons and spraying them with tear gas. The court said Turkish police dragged female protesters from hiding spots and beat them.
Turkish national Nergiz Izci said she was injured by police during the demonstrations.
"The police's hasty response to a peaceful gathering had caused mayhem and the ensuing use of disproportionate force against the demonstrators had resulted in the injuring of Ms. Izci," the court said.
The court added police admitted to hiding identification badges to avoid recognition.
The court last week said Turkish police used excessive force when responding to 2006 demonstrations in support of the militant Kurdistan Workers' Party.
Turkey has been on edge since early last month as demonstrators express frustration over plans to raze a historic park in Istanbul. Demonstrations this year have evolved into a national anti-government campaign.
