Update:  April 26, 2016, Hadi Heidari has been released from prison. He posted the following message: “Hello to freedom! By the grace of God, I was released from Evin Prison tonight after serving time… I am extremely grateful to all my friends who supported me and my family during this time. Thank you. I hope I am worthy of your kindness.”

Hadi Heidari is an Iranian cartoonist arrested in November 2015 for “collaborating with the west” after publishing a drawing mourning that month’s terror attacks in Paris. He has previously been arrested twice for his work, and has faced charges in the past such as “propaganda against the state” and “assembly and collusion against national security.”

Heidari was arrested on November 26, 2015 in his office at Tehran’s Shahrvand Daily newspaper. The newspaper is known for being reform-minded and is frequently subject to censorship from Iran’s Islamic Revolutionary Guard police force.

It is believed that Iran has used the country’s recent negotiations with western powers as justification for widespread allegations of “collaborating with the west” raised against journalists. Friends of Heidari, speaking on condition of anonymity, have suggested that his arrest was part of a coordinated legal attack on Iran’s newspapers which deviate from the conservative hardline.

The artist’s lawyer has stated that he has been called to complete 11 remaining months of a sentence over “The Blindfolded Men,” a 2012 cartoon which saw Heidari charged with “collaborating with the west.” While Heidari’s arrest came only days after he posted a cartoon to his Instagram page of a weeping face adorned with an image of the Eiffel Tower, a close friend said on condition of anonymity that the artist had been expecting his arrest for some time.

Witnesses state that police handed Heidari a warrant, the exact contents of which remain unknown, and he went along peacefully. It is yet unclear as to whether or not Heidari will face further charges for his iconic Paris cartoon.

Hadi Heidari has been relocated to Tehran’s Evin Prison, Iran’s high-security facility often used for the detention of political dissenters, artists, and other prisoners of conscience. While Heidari’s lawyer has stated that he is serving the remaining 11 months of a 2014 sentence, he may possibly face more charges. Hadi Heidari is expected to remain in Evin Prison until at least October 2016.
