Update on Women Activists arrests

Families of the women activists came to the gates of Evin Prison and were asking for the wherabouts of their families. According to this piece by www.meydaan.com, after unsuccessfully trying to get rid of the detainees families, prison officials said the detaines were being held in prison section 209. The Evin prison officials claimed that this division was under the "intelligence service" control and that they did not have any jurisdiction or authority over section 209.

My questions are, how can they be put in specialized prison divisions when they havn't even been formally charged with a crime? How many independant and separate police forces are there in Iran and which one ordered the arrests in the first place?
