The Gunners ran out 4-2 winners in a memorable meeting at the Emirates Stadium on Sunday, with Metropolitan Police afterwards confirming there were seven arrests made.
It is understood one of those arrests came after a banana skin was hurled from the away end as Pierre-Emerick Aubameyang celebrated scoring an early penalty in front of the Tottenham fans.
“Behaviour such as this is completely unacceptable and the supporter in question will be issued with a ban,” a Tottenham spokesman said.
There were also six arrests for public order offences – at least two of which are believed to be Arsenal supporters who lit smoke canisters during the match.
Aubameyang had opened the scoring before an Eric Dier header and a Harry Kane spot-kick sent Spurs in ahead at half-time.
The Gabon forward went on to equalise, with Arsenal wrapping up the points through Alexandre Lacazette and Lucas Torreira strikes.
Tottenham defender Jan Vertonghen, who had conceded the early penalty for handball, was sent off late on for a second yellow card to round off a forgettable afternoon for Mauricio Pochettino’s side.
The win sees Arsenal move fourth, ahead of Spurs on goal difference, with Unai Emery now focused on another testing examination away at Manchester United in midweek.
“Now I am thinking of the match on Wednesday in Manchester,” he said.
“It is a very big victory, we showed our supporters and we gave them the victory because it is a very special match against Tottenham, for us it is special also.
“But above all it is three points, like against Bournemouth. We are happy, we are enjoying, but shocked because Tottenham are on 30 points like us.”
The unrest was not restricted to the stands as the two sets of players had to be separated following Dier’s equaliser on a feisty afternoon in north London.
The England midfielder celebrated by putting his finger to his lips, with Arsenal substitute Stephan Lichtsteiner reacting angrily to the gesture and referee Mike Dean showing Dier a yellow card.
Pochettino ran down the touchline to help calm matters, with Dier afterwards defending his own actions in the incident.
“I had my back to it all so I’m not too sure what happened,” he said of the scuffle.
“But this is football. It’s a derby. football is all about emotion and I don’t understand how I can get a yellow card in that situation.
“It baffles me because if you take the emotion out of football you’re going to destroy the game for everyone.
“The ref said he gave me the yellow card because it was because of me that the whole thing started.
“If you watch it, we’re celebrating, I don’t leave the pitch at any point and some of their players that are on the bench come to us.
“Their players approached us. I don’t know what’s wrong with it. But it doesn’t matter. It wasn’t because of that we lost.”
The Argentina international was held out of Saturday’s 3-1 win over Bournemouth with a muscle injury, and he is doubtful to face Watford and Chelsea this week after Pep Guardiola revealed club doctors warned him Aguero could be ruled out until January if he aggravated the problem.
“The doctors told me (on Friday) Sergio cannot play,” Guardiola said. “If he plays, maybe it’s four or five weeks off. In that situation, this month, with a lot of games, he was not safe.”
City’s all-time top scorer therefore seems unlikely to make the trip to Vicarage Road on Tuesday or Stamford Bridge on Saturday.
“Right now, I’m not quite sure,” Guardiola said when asked about Aguero’s availability. “We’ll see. That’s why I said before day by day we see. I speak with the doctors every day, they make a report and a briefing. They say ‘ready’ or ‘not ready’ and we decide.”
Gabriel Jesus started against Bournemouth in Aguero’s absence, but was unable to get on the scoresheet.
Though he scored a hat-trick against Shakhtar Donetsk last month, Jesus has scored only one league goal for City in a largely frustrating season to date.
Aguero’s form has limited his playing time of late, but the 21-year-old said he was ready to contribute if needed following his own injury concerns which saw him miss last week’s Champions League win over Lyon.
“I’ve been training really hard, maybe that’s why I felt something in my groin last week,” Jesus said.
“Unfortunately I was out of the Champions League match that I really wanted to play.
“I always make it clear for Pep that I’m here to help the team regardless of how. Obviously that I want to play more minutes, but I respect who is playing at the moment. Hopefully I make the best out of my next chance.”
For his part, Guardiola praised Jesus’ all-round contribution against Bournemouth and said he had no concerns that the Brazil international’s goal drought would continue much longer.
“We just relax,” Guardiola said. “It’s work, this work ethic he has. Always I said to him: when you work like he works on the pitch, always we will sustain him. We will always be there.
“Football is not for one player the reason why he plays bad. He helps us a lot. Gabriel is a delight. He’s young, the same as the other ones, he will improve because has the desire to improve and that is important. He helped us a lot.”
Everton goalkeeper Jordan Pickford apologised to fans for his blunder which handed Liverpool a 1-0 victory in the Merseyside derby at Anfield but insists he is mentally strong enough to bounce back.
The England international misjudged a looping, spinning mis-kicked shot from Virgil Van Dijk, allowing it to bounce onto the top of the crossbar instead of tipping it behind.
The ball dropped down for Divock Origi to bundle home the winner in the fourth minute of stoppage time.
“I will say sorry to the Everton fans again, because I know how much it means to them,” said the 24-year-old, who also went over to apologise to the visiting supporters at the final whistle.
“As players, we know how much it means to us. Look, you make mistakes every now and again.
“The ball spun and as I tried to flick it over, my hand hit the bar. I think it is the Everton luck when we come to Anfield.
“It’s not something you can learn and train and get better from. It’s just a freak incident. You move on and get better.
“There is always a case as a goalkeeper… if you make an error it will lead to a goal. Unfortunately, it has been me today.
“There’s nothing I can do about it now. I’m strong mentally and I will get over it.
“I will be ready for Newcastle on Wednesday. We know we held our own against a good Liverpool side for 96 minutes.”

It was a harsh end to a derby in which both Pickford and his opposite number Alisson had produced good saves to keep their rivals at bay.
Alisson had some consoling words for Pickford at the final whistle – and that was appreciated.
“I couldn’t hear what he said exactly but it was nice and it showed a bit of respect,” he added.
“That football game was played with respect, there was nothing malicious – just a very good game of football.
“It’s unfortunate for me but I think it was a good game for everyone on outside to watch.”
Pickford is determined not to let the error derail what has been a good year for him, having established himself as England manager Gareth Southgate’s first-choice by performing well at the summer’s World Cup.
“I don’t sleep well after many games, really, but we have got a game on Wednesday and I will show people what I can do,” he said.
“You can’t practice what happened there in training. You just have to get on with it and I will show you my character.”
