A Concordia University professor says she believes Iranian authorities have fabricated charges against her colleague, Homa Hoodfar, whom she calls an “asset to Iranian society.â€

Hoodfar was detained in Iran on June 6 and placed in Evin prison. Her niece, Amanda Ghahremani, told Â鶹´«Ã½ in June that a newspaper with links to Iran’s Revolutionary Guard said she was accused of "fomenting a feminist soft revolution.â€

Ghahremani said Monday that state media are now reporting that Hoodfar is being investigated for “dabbling in feminism and security matters.†It is still not clear whether she has been formally charged.

Genevieve Rail, a women’s studies professor at Concordia University, told Â鶹´«Ã½ Channel that Hoodfar is indeed a feminist, but “she is working for the well-being of Iranian women and Muslim women in many countries, so that is certainly not a cause for her imprisonment.â€

Rail said Hoodfar has helped to “debunk all the myths that we may have here in the west about Muslim women†during her three decades in Canada.

“The kinds of research that she is dealing with are an incredible asset to Iranian society and Muslim societies,†Rail added.

Rail said she is concerned that Hoodfar is being held in Evin. Montreal photojournalist Zahra Kazemi died there in 2003 after she was raped and tortured.

Hoodfar, 65, was born in Iran. She also holds citizenship in Ireland.
