Iranian cartoonist Hadi Heidari with his daughter.

Egyptian cartoonist Tamer Youssef has contacted me to confirm that Hadi Heidari, the Iranian cartoonist arrested in Tehran, has been released from prison.

Heidari was arrested on October 22 after participating in a religious ceremony in honor of political prisoners. He was later joined in prison by his wife, Negar Sayeh, who works for a variety of media outfits.

Cartoonists and artists from around the world have been following the news of Heidari's arrest, and were excited to hear of his release.

"This is great news! Well done on an excellent awareness campaign," John Curtis, a South African designer, posted on the Free Hadi Heidari NOW! Facebook page. "It's great to see how cartoonists from all over the world have stood together against this kind of tyranny."

I'm hoping to interview Hadi when things settle down. For now, I'll provide more information as I receive it.
