The father of a graduate student at California State University-Northridge says his daughter has been freed on bail after spending nearly a month in an Iranian jail.

Reza Momeni told the Los Angeles Times that his 28-year-old daughter, Esha Momeni, was released on Monday but isn't allowed to leave the country.

The student, a dual U.S. and Iranian national, was visiting Tehran to research a master's thesis on the women's rights movement in Iran when she was arrested Oct. 15 on a traffic violation.

She was later charged with acting against national security and propagating against the system, which could carry lengthy prison terms.

Reza Momeni says he put up the deed to his family's Tehran apartment to cover her $200,000 bail.
