Hossein's arrest confirmed by his sister

It has been confirmed that Hossein Derakhshan, the Father of the Iranian Blogging Revolution, was arrested last week in Tehran.  Sanam Dolatshahi, an Iranian student at the University of Florida, writes in her English-language blog Lady Sun :

My friend Nazli finally got the OK from Hossein Derakhshan's sister, Azadeh Derakhshan, to publicly announce that Hossein Derakhshan, one of the first Iranian bloggers, was arrested on the afternoon of November 1, in Tehran.

I am quoting this news from Nazli Kamvari, a friend of Hossein Derakhshan and an Iranian blogger living in Toronto, who has been directly in touch with Hossein's sister and just wrote about this news in her Persian blog.

Jahan News reported that he was arrested for spying for Isreal but the Iranian government has yet to issue any official public statement regarding the reason for Hossein's arrest.  

This is the question we must have answered right away.  Why was he arrested?  What has he done to warrant his imprisonment?  If you have any ideas about how to get this question answered, please feel free to leave them in the comments below, or contact us at for.hoder@gmail.com.
