The Football Association will take no action against Arsenal winger Theo Walcott for his gesture towards Tottenham Hotspur fans during Saturday's FA Cup tie between the teams.
Walcott made a 2-0 sign with his hands as he was stretchered off near the end of Arsenal's third-round win at the Emirates Stadium after being hit by objects thrown from the away end.
Despite taking no disciplinary action against the England international, the FA has confirmed that it has contacted both clubs to "seek their observations" in relation to the behaviour of supporters.
"The FA has contacted both Arsenal and Tottenham to seek their observations in relation to objects being thrown from both a home and away section of the crowd at different times during Saturday's FA Cup tie," read an official statement.
"The FA condemns any such acts and will liaise with both clubs and the Metropolitan Police to identify those responsible and support the strongest sanctions available, including life bans.
"Meanwhile, in relation to the same fixture, The FA has contacted Arsenal's Theo Walcott and reminded him of his responsibilities regarding a 'scoreline' gesture he made in front of away supporters during the game.
"The FA will not be taking any further disciplinary action."
Arsenal return to action on January 13 when they travel to Aston Villa in the Premier League.
