A FATHER suffered head injuries after a brutal gang attack in the audience of the James concert in Princes Street Gardens.
The 52-year-old had been enjoying the gig when a nearby group made comments to several family members who were with him.
He tried to intervene to “protect” his relatives – only to be subjected to a violent assault.
The gang repeatedly punched and kicked the man, who suffered deep gashes to his head.
He was taken to Edinburgh Royal Infirmary, but was released later that night.
Detectives are now keen for witnesses to the assault to come forward, and say they have launched a “robust” investigation.
The victim and his family had been in the centre of the audience area when the disturbance broke out at around 9.30pm last Wednesday.
Detective Constable Andrew Cory, who is leading the probe, said the victim and his family were “shaken-up” from the ordeal and were keen to find out who was responsible.
Det Con Cory said that the man, who said he did not want to speak to the press, had been “protecting his family” before he was attacked.
The gang is not believed to have known the victim or the relatives he was with, none of whom were children.
None of the other family members injured.
Det Con Cory said: “It erupted into a disturbance and it’s resulted in serious injury. He was kicked and punched by a number of people. Stewards initially got involved and there was a police presence at the event.
“Our inquiries are under way and we are now appealing to anyone who attended this event or who saw this incident to please contact police.”
It is not yet known whether the gang were all-male or whether any women were involved.
And it is understood that detectives are trawling through CCTV footage to see if they can piece together the exact circumstances of the incident.
Officers are particularly keen to trace a male described as white with a large build, short grey hair, wearing a red checkered shirt and in his 40s or 50s.
Last Wednesday’s James gig was part of the Magners Summer Nights series at the Ross Bandstand in Princes Street Gardens.
The Mancunian band opened a three-day concert programme, which also featured The Flaming Lips and The Waterboys.
James enjoyed a run of 20 top 40 hit singles after emerging as part of the indie movement in the mid-80s.
Hits include Sit Down, She’s A Star, and How Was It For You? Their album sales stand at 12 million.
The serious assault is believed to be the only police incident which took place during the James gig.
Promoters Regular Music, who were behind the concerts, said it would be inappropriate to comment on the case while a police investigation was ongoing.
Anyone with information should contact Police Scotland on 101 or Crimestoppers on 0800 555 111.
