(CNN)A Tottenham fan has been arrested for throwing a banana skin onto the pitch as Pierre-Emerick Aubameyang celebrated Arsenal's opening goal in Sunday's bad-tempered North London derby.
The 29-year-old from Gabon scored Arsenal's first from the penalty spot in the 10th minute before celebrating in front of the traveling Spurs fans at the Emirates Stadium.
Several objects were thrown in Aubameyang's direction, including the banana skin.
"Behavior such as this is completely unacceptable and the supporter in question will be issued with a ban," a Tottenham spokesperson said in a statement.
In total, six arrests were made Sunday in relation to the match, a Metropolitan Police statement said.
The Gunners won the match 4-2 to leapfrog their local rivals into the top four, coming from 2-1 down at half time to extend their unbeaten run to 19 matches.
Eric Dier's strike and a Harry Kane penalty had seemingly swung the game in Spurs' favor after Aubameyang's opener.
But his stunning second goal -- his 10th in the Premier League this season -- hauled Arsenal level early in the second half, before Alexandre Lacazette and Lucas Torreira secured a vital three points.
Both sets of players clashed after Dier's equalizer, prompting Spurs boss Mauricio Pochettino to sprint down the touchline to act as peacemaker.
Tottenham's misery was compounded five minutes from the end when Belgian international Jan Vertonghen was sent off for a second yellow card.
For Arsenal's new manager Unai Emery it was a first victory over a top-six rival. Next up is a trip to Old Trafford
