Galatasaray have been fined €50,000 by UEFA and ordered to pay damages to Arsenal following the Champions League encounter between the two sides earlier this month.
UEFA initially launched disciplinary proceedings against both clubs.
Arsenal were charged with “insufficient organisation (lack of body searching)” after fireworks and missiles were smuggled into the Emirates Stadium and thrown on the pitch during the Gunners 4-1 win on October 1.
Several flares were thrown onto the pitch from the section where the Galatasaray supporters were located towards the end of the first half, causing the game to be briefly halted.
Metropolitan Police confirmed there had been two arrests for entering the ground with flares.
UEFA released a statement confirming the fin and also ordered Galatasaray to reach a settlement with Arsenal over damages.
The statement read: “The Turkish team have also been ordered to contact Arsenal FC within 30 days for the settlement of the damages caused by its supporters.”
Arsenal will travel to Istanbul on December 9 for their second encounter with Galatasaray in the last group game.
