Arsenal have vowed to hold an inquiry into a missile-throwing incident during their fourth round FA Cup tie against Liverpool yesterday and said the thrower would be banned from their ground for life.
Today's newspapers also reported that Liverpool's Jamie Carragher, who was sent off with 20 minutes from time after throwing a coin back into the crowd, could face legal action after a fan was hit.
Arsenal beat the holders 1-0 in a hard-fought encounter marred by red cards for the home side's Martin Keown and Dennis Bergkamp, as well as the Liverpool defender.
The Guardiansaid police had confirmed they received a complaint about the incident and had taken statements from fans. The paper also said Arsenal could face an FA fine over the incident.
The Sunsaid the police were ready to join the FA in examining Carragher's actions.
Arsenal said what happened was unacceptable and they were appealing for help in identifying those responsible for throwing the objects on the pitch.
Carragher has apologised for his part in the incident, after receiving criticism for his reaction from assistant manager Phil Thompson.
"No matter what the physical or verbal provocation, I shouldn't have reacted like that . . . I was frustrated and did it without thinking in the heat of the moment," he said.
