Twenty-six German men who were arrested after a violent brawl broke out in Liverpool have been released, police said.
Chairs and missiles were hurled through the air as chaos descended on Concert Square in the city centre shortly after 11pm on Wednesday.
Merseyside Police said 26 German nationals were arrested on Thursday to prevent a breach of the peace but had since been released.
Nine other men – including five German nationals, a Spanish national, an Iranian and two Liverpool men, aged 23 and 28 – were still being questioned after being arrested on suspicion of violent disorder offences.
One man was in a critical condition after suffering a head injury in the clash, which involved members of the public and door staff.
Footage on social media showed the melee spilling into the street, with one man appearing to be body-slammed by a bouncer.
The violence came the night before Italian football fans arrived in the city for Everton’s Europa League fixture against Atalanta.
Detective Chief Inspector Cheryl Rhodes said: “We are keen for anyone who was in the area at the time or has information on this incident to come forward and speak to police, or Crimestoppers.
