Nine people have been arrested after last night's Champions League semi-final between Liverpool and AS Roma.
They were arrested on suspicion of offences include attempted murder, affray, assault, possession of weapons and drugs, criminal damage, and being drunk and disorderly.
One man, believed to be a Liverpool fan, is in a critical condition in hospital after being assaulted near the ground, in what police believe to be an altercation between Liverpool and Roma fans.
Two men, aged 25 and 26 years from Rome, have been arrested on suspicion of attempted murder and have been taken to a police station where they will be interviewed by detectives.
Police are also investigating the use of flares outside Anfield stadium on Arkles Lane prior to the game.
They are reviewing CCTV footage, body worn camera footage and working with the club to identify those involved.
