Security officers arrested Valizadeh, a blogger and editor of the Web site Baznegar, in Tehran, according to news reports. He was detained after President Mahmoud Ahmadinejad’s office complained about an online article describing the presidential security team’s purchase of four bomb-detecting dogs from Germany, according to news reports. Other media had covered the story as well, including The Guardian of London.
Valizadeh was being held at Tehran’s Evin prison. Charges were not immediately disclosed, according to news reports.
