The men, three Spaniards and one Frenchman of North African origin, are all aged between 20 and 30.
Three youths suffered stab wounds in the incident, and one was left in a serious condition.
The Police are still searching for a British citizen who is thought to have been responsible for the stabbing.
Witnesses claim that the man, who was with one of the groups involved in the fight, “appeared to be very nervous” and “repeatedly asked for someone to take him home because he had no idea what had happened”.
