In a decision dated 13 April 2011, the EU placed Ahmad Reza Radan on its human rights sanctions list for its role in widespread and grave violations of the rights of Iranian citizens. According to this decision, Radan will be banned from entering the countries of this union and all his assets will be confiscated in Europe. According to the EU statement, Ahmad Reza Radan has been sanctioned for his responsibility in "beating", "killing" and "arbitrary detention of protesters".

According to this decision, Ahmad Reza Radan's potential assets in the United States will be seized and he will be barred from entering the country.
