A brutal brawl between two groups of yobs, including brothers from Accrington, was captured on CCTV.
The shocking scenes have now been used in court to secure convictions against those involved in the violence.
Five men and a teenager exchanged punches and kicks after an early morning disturbance outside the Printworks entertainment complex in Manchester spilled onto Metrolink tram lines at nearby Shudehill.
The graphic footage shows men being kicked in the head and face as they lay prone on the floor.
In one attack, one of the yobs stamped down on another’s leg in a bid to break it to stop him getting back up, a court was told.
The violence flared, Manchester Crown Court heard, after three Polish men ‘took umbrage’ with a Latvian man talking to a group of English women in Russian. He was with two other Latvian friends and a ‘verbal dispute’ ensued.
Neil Beckwith, prosecuting, said: “It is the Polish group who are described as the aggressors.”
Two of the Latvian men were trained in martial arts and kick-boxing, Mr Beckwith added. He said: “There seems to be some goading and barracking and it descends into a large brawl in which all are involved.”
The court heard that a number of the defendants ‘adopted boxing stances’. The footage, recorded in the early hours of July 5, shows men being viciously kicked and punched after being knocked to the ground.
Mr Beckwith added: “Police were called after being made aware by the CCTV control centre. The Latvian group fled and the Polish group were injured. They were all involved in the incident. It was appropriate to proceed against all of the males.”
One of them, Konrad Wegrzynowski, was punched in the face and suffered a fractured cheekbone, but there were no other injuries.
The six pleaded guilty to affray.
They are brothers Dominik Wegrzynowski, 30, of Lonsdale Street, Accrington; Konrad Wegrzynowski, 31, of Lonsdale Street, Accrington; Kryspin Wegrzynowski, 33, of Meadow Way, Lancashire; Arturs Nefjodovs, 29, of Blue Bell Avenue, Moston; Eduards Tjabuts, 24, of Briar Hill Avenue, Little Hulton, Salford, and a 17-year-old from Salford, who cannot be named because of his age.
Judge Suzanne Goddard QC called their actions disgraceful. She told them: “It is no doubt a matter of shame to you and your families that you are standing in a dock of the crown court.
“All of you behaved disgracefully. This sort of behaviour is not acceptable. It is clear that something had been said and following that, there was a confrontation which spilled out onto the tram lines. No one chose to walk away.”
Judge Goddard said she could suspend their prison sentences because of their lack of previous convictions and ‘hard-working’ attitudes.
The 17-year-old, a college student, was sentenced to a six-month youth rehabilitation order with a three-month curfew between 10pm and 7am. The other five were all jailed for 12 months, suspended for two years, and ordered to carry out 200 hours of unpaid work.
