A Tottenham supporter was arrested on Sunday after throwing a banana skin onto the pitch during the Spurs' feisty north London derby with Arsenal at the Emirates Stadium.
According to a report from The Telegraph, the fan launched the banana peel toward Arsenal's Pierre-Emerick Aubameyang after the striker netted a 10th-minute penalty.
"Behavior such as this is completely unacceptable and the supporter in question will be issued with a ban," a Spurs spokesman said in a statement.
Six others were also arrested on Sunday for similar behavior, including two Arsenal fans who lit smoke canisters in the second half.
