Arsenal manager Arsene Wenger has condemned the disturbances by Gunners' fans following the end of Wednesday night's Capital One Cup victory at Tottenham, and vowed the club will fully cooperate with the authorities to help identify those responsible.
Midfielder Mathieu Flamini struck a stunning late winner to secure bragging rights in the north London derby.
However, the celebrations were overshadowed by disturbances which saw a minority of the travelling supporters in the corner of the South Stand ripping down hoardings of Tottenham club slogans, with police and stewards forced to intervene.

Arsenal are now working with both Tottenham and the authorities, with banning orders a likely outcome for any offenders.
Wenger was disappointed the incident had taken the shine off what was a positive response to a difficult spell following defeat at Dinamo Zagreb in the Champions League and also in a fiery clash at Stamford Bridge last weekend.
"We cooperate completely with the authorities to sort that out. We don't want any violence," said Wenger, who takes his side to Leicester on Saturday.
"I don't really know what happened but we are the disposal of the authorities to help them to sort it out."
Wenger feels the performance at White Hart Lane showed his squad, which saw several players rotated, have the needed character to get their campaign back on track.
He said: "It shows that we have a big squad at a very strong level and I have always considered that because I have confidence in every single player.
"The team who played at Tottenham basically played at Zagreb the week before. That shows I have great confidence in my players."
Alexis Sanchez has yet to find the net in his eight performances this season.
Wenger admits the Chile forward is working off a hangover from the summer's Copa America success and felt he perhaps should have been given more time to recover.
"I think I played him very early before he was completely fit, physically, that is one explanation," said Wenger.
"The second is that every player who has won a big trophy with the national team takes some while to settle and come back to his best. These are the two main explanations for me.
"Physically he is not completely ready, coming out of a big achievement and that takes time.
"I don't worry for Alexis Sanchez. Even when he doesn't score he is still a major threat for everybody and I am confident he will score very soon."
