Arsenal have identified an image of the fan who “embarrassed” the club by throwing a bottle at Dele Alli during their defeat to Tottenham.
The club have been studying CCTV footage and are working with the Metropolitan Police to apprehend the culprit.
“We do not tolerate any anti-social, discriminatory or violent behaviour at Arsenal Football Club. Anyone identified will receive a lengthy club ban and their details will be passed to the police to commence legal proceedings.”
It is understood the FA will support any criminal proceedings brought against the thrower and will push for a banning order.
However, as it is one individual at fault rather than more widespread disorder involving a number of fans, it is usual procedure for the FA in these circumstances to offer support to the investigation, rather than seek to punish the club.
