Abdolreza Tajik has been a journalist and human rights activist since the 1990s. He has worked with publications such as Khordad, Fatah, Bonyan, Bahar, Etemad, Tose'e, Kargozaran, Shargh and the ILNA News Agency. He was also a member of the Iranian Association of Human Rights Defenders. Tajik was sentenced to six years in prison on security related charges.

On February 17, 2009, Abdolreza Tajik was banned from leaving the country. At that time, he was scheduled to travel to Spain to deliver a speech at a seminar on Iran “after the [1979] Revolution,” but he was prevented from leaving Imam Khomeini International Airport in Tehran by security agents.

Tajik spoke in an interview with Radio Farda about the matter, saying, “I had wanted to travel to Spain to give a lecture at the “Iran: Thirty Years After the Revolution” seminar. However after the border police had stamped my passport with my exit visa, I was waiting to board the plane and the airport loudspeaker requested that I report to the police.” 

He continued saying that, “At the same time, someone in the waiting room of the terminal was calling my name and searching for me. When I reported myself to the police, they stamped my passport with the travel ban stamp and told me that I needed to report to the Security Deputy of the Revolutionary Courts.”

Abdolreza Tajik and numerous other civil society activists and journalists were arrested following protests over the disputed 2009 Iranian presidential election.

Tajik was arrested for 46 days on the accusation of “disturbing public order” but he was later released from Evin Prison on August 1, 2009, on bail for the amount of 100 million toman. He was arrested for a second time after the Ashura Protests, on December 26, 2009, on the accusation of “propaganda activity,” and held for 60 days in Section 209 of Evin Prison, operated by the Ministry of Intelligence. A third arrest came on June 12, 2010, when Tajik was arrested while reporting to the Ministry of Intelligence Prosecutor’s Office. 

On July 24, 2010, news of a new charge against Abdolreza Tajik's, “slander,” was published in the media. Parvin Tajik, the journalist's sister, heard the news during a meeting with her brother on July 15, and sent a letter to Sadegh Larijani, then head of the judiciary, asking him to follow up on the matter. 

Parvin Tajik quoted her brother as saying that he had been charged with “slander” on the first night of his arrest in the presence of the deputy prosecutor and the investigator of the First Branch of the Prosecutor's Office.

In the fall of 2009, Parvin Tajik was arrested and sentenced by Judge Mohammad Moghiseh of Branch 28 of the Revolutionary Courts of Tehran to one and a half years in prison on the accusations of “propaganda against the state” and “disturbing public opinion.” Parvin Tajik was arrested and sentenced on these charges for describing her brother's condition and arrest in interviews with Persian-language media outside Iran.

On December 9, 2010, Reporters Without Borders named Abdolreza Tajik the best journalist of 2010 and said it hoped the award would pave the way for his release.

Tajik’s trial took place on December 19, 2010, in Branch 26 of the Revolutionary Courts of Tehran, presided over by Judge Yahya Abbas Pirabbasi. He was accused of “propaganda against the Islamic Republic of Iran,” “Membership of the Iranian Association of Human Rights Defenders” and “actions against national security.” Tajik was sentenced to six years imprisonment. 

On December 22, 2010, Tajik was temporarily released from prison on bail for the amount of 500 million tomans.

On October 20, 2011, he wrote that his six year prison sentence had been upheld by Branch 54 of the Tehran Court of Appeals. However, before Abdolreza Tajik’s sentence could be enforced, he left the country and went to France. 

On June 9, 2012, in an unprecedented move, the Iranian judiciary enforced Tajik’s bail of 500 million tomans. His family were therefore forced to pay the bail and deposit to prevent the seizure and confiscation of their house.

Abdolreza Tajik currently resides in Paris, France.
