The fight took place around midnight on Thursday night. Police are investigating the incident as murder and attempted murder. Two men in their 20s were arrested on Thursday and have since been remanded in custody. Two more people, also in their 20s, are now suspects, several media outlets reported on Friday.
"Yes, now we have a total of four young people deprived of their liberty. All of them are jointly and in agreement suspected of murder and attempted murder," said district prosecutor Johan Fröjelin to Göteborgs-Posten.
The injured man's condition is not life-threatening, according to SVT News West.
