A violent clash between football fans broke out in Manchester on Wednesday, ahead of Manchester City's Champions League group match against Spain's Sevilla at the Etihad Stadium.
Photographs and footage on social media show chaotic scenes as chairs were thrown in Exchange Square in Manchester city centre.
Police confirmed that they were called to the scene shortly before 3.30pm on Wednesday afternoon, and a group of fans dispersed in all directions as the officers arrived. Greater Manchester Police (GMP) tweeted that they had arrested three Polish men on suspicion of violent disorder, while another was later arrested after police found him hiding in a restaurant.
One man was injured in the fighting, and a GMP spokesperson said that his head wound was treated at the scene by paramedics.
It has been suggested by reports that some of those involved in the fighting were wearing the colours of Slask Wroclaw, the Polish club whose fans have recently clashed with those of Sevilla.
