A newly published surveillance video shows the attack on a young woman who died after defending two teenage girls from male harassment and whose death has been mourned with candlelight vigils across Germany.
Daily paper Bild published the video on its website today calling on witnesses, including the teenage girls, to come forward with more information about the attack on November 15 in front of a restaurant in Offenbach.
Student teacher Tugce Albayrak died on Friday, her 23rd birthday, after her family gave doctors permission to switch off her life support.
Albayrak had been in a coma after reportedly being struck in the head in the altercation.
Police say an autopsy will be performed today to determine the cause of death.
