The Football Association have welcomed Everton's initiative to identify the thug who threw an object at Manchester United goalkeeper Roy Carroll during yesterday's FA Cup tie at Goodison Park.
The fifth-round match was held up in the second half when Carroll was struck by a missile - believed to be a coin - thrown from the crowd.
A number of other missiles were also hurled, including a mobile phone, and after the match violence spilled onto the surrounding streets.
Police made 33 arrests and five officers were injured - one of them requiring hospital treatment - after trying to break up groups of fighting supporters who clashed in the Everton Valley district of Liverpool.
FA head of media Adrian Bevington told The Press Association: "We are in the process of speaking to the club and to Merseyside Police. "We welcome the comments from Everton Football Club immediately following the match and their desire to have the culprit identified and then for the police to deal with them.
"Individuals who throw missiles must face action from the police and then through the courts, and then receive banning orders to prevent them attending any football both at home at abroad."
Security had already been high for a match which saw the return of England striker Wayne Rooney to his former club for the first time since his acrimonious £27million move to United last summer.
The atmosphere had been intense from before kick-off and a large-scale police presence was required to escort the away supporters from stadium to the city centre after the match.
