According to press reports,[5] two officers of a police patrol had been engaged in a minor verbal clash with a small group of people in the street, outside a shop. On driving away in their police car, they were then confronted by another group attacking their car at a street crossing. The officers were ordered to disengage and withdraw from the confrontation. However, on finding a detachment of riot police stationed in waiting in a street nearby, they decided to leave their car there and return to the scene on foot to confront the attackers. Faced with a hostile group of youths and after some exchange of verbal abuse, one of the officers (Epaminondas Korkoneas) then reportedly fired, killing one of the protesters, 15 year old Alexandros Grigoropoulos.
