Clashes broke out between protesters and police during protests to mark the 17th anniversary of a teenager being killed by police.⁣ ⁣ In 2008, the fatal police shooting of 15-year old Alexandros Grigoropoulos on an Athens street triggered Greece's worst riots in decades.⁣ ⁣ The police officer was sentenced to life imprisonment but was released earlier by an appeals court. ⁣ ⁣ Riot police monitoring Saturday's demonstrations used teargas and flash bombs and arrested several protesters. ⁣ ⁣ #AthensClashes #Grigoropoulos17 #GreeceRiots #ProtestChaos #Athens #Greece #Protest
