The four suspects aged between 19 and 21 faced charges of grievous bodily harm, prosecution spokesman Martin Steltner said late on Wednesday. Two of them also faced manslaughter charges for kicking and beating the victim, identified as Jonny K., at the city’s Alexanderplatz square late one evening in October.
A police investigation determined there was no intent to kill the victim, but his death sparked a public discussion about youth violence.
Three of the four suspects have been held since last autumn while two others, Onur U. und Bilal K., fled to Turkey.
Authorities in Berlin have since contacted their Turkish counterparts to demand their extradition, which could be problematic if they only hold Turkish citizenship.
“We are continuing to do everything we can to ensure they are put before a court,” said Berlin’s Justice Minister Thomas Heilmann.
