Arsenal have identified an image of the individual they suspect threw a plastic bottle at Tottenham star Dele Alli and are working with the Metropolitan Police to apprehend them.
Alli was struck on the head by the projectile, with Spurs leading 2-0 in the 73rd minute of the EFL Cup quarter-final at Emirates Stadium on Wednesday.
The Metropolitan Police stated on Thursday that no arrests had been made in relation to the incident but it was working with the Gunners on the issue.
Arsenal apologised to Alli in a statement and suggested a lengthy ban could be in store for the offender, who they believe has been identified via CCTV footage.
“Behaviour of this type has no place at Emirates Stadium and after analysing CCTV footage, which showed him leaving the stadium after throwing the bottle, we have identified an image of the suspect. We are liaising with the Metropolitan Police and investigations continue in order to apprehend the culprit.
“We are not responsible for the actions of one individual but send our apologies to Dele Alli and everyone at Tottenham Hotspur for this incident.
