Now the Serbian SuperLiga side have moved to distance themselves from those supporters, claiming their actions make the country’s fight to stamp out discrimination "worthless".
UEFA has confirmed that it has opened disciplinary proceedings against Partizan.
In a statement UEFA said: "Disciplinary proceedings have been opened against FK Partizan for racist behaviour of their supporters, field invasions by supporters, setting-off of fireworks and use of laser pointer.
"The case will be dealt by the UEFA control, ethics and disciplinary body on October 3."
Partizan admitted it had been embarrassed by the banner. A statement on the club’s wesbite read: "Dear football aficionados in Serbia and Europe," it read.
"The football match between Partizan and Tottenham was eagerly awaited in our city and we watched fine performances from both teams in a fair-play sporting atmosphere.
"But this game was marred by malicious act of certain individuals who made all the efforts from our players and our club to prove we deserve our spot in football Europe worthless.
"FC Partizan resolutely disavows with anti-Semitic banner displayed yesterday. The message displayed on that banner is completely opposite to preferences and opinions of almost all citizens of Serbia and Partizan fans.
"It is absolutely absurd to link a club that was founded after the WWII on anti-fascist principles and after the battle of people of Europe with anti-Semitism and similar dark and anti-civilisation impulses.
"We fully condemn perpetrators of this mindless act, not only of anti-Semitic nature, but one that represents hatred of Partizan and Serbia as well.
"We believe this vicious action will not spoil our sporting friendship with Tottenham and football aficionados in Great Britain. In cooperation with competent authorities, Partizan FC will do everything to locate, trial and ban those perpetrators from sporting fields.
"We apologise to everyone who found themselves insulted and upset by this banner.Once again, we point out that such banner message is completely opposite to history and tradition of our club, and our fans’ aspirations."
