An 18-year-old man from Wolverhampton was also arrested on suspicion of grievous bodily harm, violent disorder and possession of cannabis. These four men have now been released on police bail until Monday February 27
A 19-year-old man from Huntingdon and a 22-year-old man from London have also been released on bail until March 23.
All the arrests took place in Cowgate and police cordoned off areas of Bridge Street and Wentworth Street between Rivergate and Cowgate where blood could be seen on the ground following a chase.
Police have said multiple bladed weapons were used in the attack. Three of the men were injured in the incident.
Anyone with information is asked to contact police on 101, or Crimestoppers, anonymously, on 0800 555 111.
