Heidari runs the web site linked to above, contributes to several newspapers firmly in the political reform camp and was recently cultural editor at the banned newspaper Etemad-e Melli. A number of that publication's contributors are also in prison. RSF says that Heidari was picked up during a religious ceremony honoring political prisoners in the home of one such prisoner.

Heidari was born in 1970; a gallery of his work can be seen here.
