From pat/THA:
"short version, he was talking to a girl, then these guys showed up, one of them started insulting him, then another one hit him in the face without warning.
gustav and the second guy got into a fight, then the other one came up from behind and hit him on the head with the beerbottle.
gustav fell backwards and got hit with a secondbottle.
then he went down. the guys who did this rushed and got out.
he was bleeding terribly from his head and they took him to the restrooms.
police and ambulance came..."

*versión corta, que estaba hablando con una chica, estos chicos se presentaron, uno de ellos comenzó a insultarlo, luego otro le golpeó en la cara sin previo aviso.
Gustav y el segundo chico tuvo una pelea, entonces el otro se acercó por detrás y le golpeó en la cabeza con la botella de cerveza.
Gustav cayó hacia atrás y lo golpeó una segunda botella.
los tipos que hicieron esto salieron precipitadamente.
estaba sangrando terriblemente de su cabeza y lo llevaron a los baños.
