LIVERPOOL -- UEFA have opened up disciplinary proceedings against Liverpool in regards to the events that surrounded Wednesday night's Champions League tie with Manchester City.
On Thursday afternoon, Liverpool were charged with four separate offences -- the setting off of fireworks, the throwing of objects, acts of damage and crowd disturbances -- by European football's governing body.
The charges of acts of damage and crowd disturbances are in relation to the damage the Manchester City team bus was damaged as it approached Anfield ahead of the first leg of the quarterfinal.
City were unable to use the coach for the return journey to Manchester as it was damaged when some Liverpool supporters threw objects towards it.
The case will be heard by the UEFA Control, Ethics and Disciplinary Body on May 31, which takes place five days after the Champions League final in Kiev, Ukraine.
Liverpool issued a statement shortly before kickoff on Wednesday, apologising to the Manchester club and saying "the behaviour of a number of individuals was completely unacceptable" and that they would "cooperate fully with the authorities to identify those responsible."
Meanwhile, Merseyside police are appealing for any footage of City's arrival after two officers were injured. Manchester City assistant coach Manel Estiarte posted footage from inside the bus after the game.
