In a phone interview, Shahrzad Mir-Qolikhan said she was held in solitary confinement for a week.
She added that on October 23 she was removed from the compound and taken to a solitary housing unit colloquially known as SHU and held there for a week.
She said that she was confined to a cell where the most dangerous criminals are kept, noting that she was never told why she had to go through the ordeal.
She was also refused access to her legal papers, including letters to the president of Iran and the United States, the report said.
"I was insisting and begging them just to let me make one single phone call to my family because they're gonna be worried about me…" she added.
Shahrzad Mir-Qolikhan was detained in the US in December 2007. Her ex-husband, Mahmoud Seif, had allegedly tried to export night-vision goggles to Iran from Austria.
She was sentenced to five years of imprisonment by a Florida federal court in absentia.
Earlier this month, Melika and Melina Mir-Qolikhan, the teenage twin daughters of the innocent Iranian woman, along with their grandmother Belqis Rowshan, appeared on Iranian English language press tv channel and asked Obama to release their innocent mother.
Later, Shahrzad's mother unveiled new details about abuse, torture and cruel treatment of her daughter by the US prison guards and jailors, and stressed that her daughter is held against the law since her retrial in the US violated the international and US laws.
Belqis Rowshan said in an interview at the time that her daughter was initially sentenced to 52 days of imprisonment by an Austrian court in 2005 and her case was closed after she served her prison term.
"Again and after a short period, a US court sentenced Shahrzad to five years of imprisonment for the same case, while based on the international laws courts are not allowed to issue two (consecutive) rulings for a single case," Rowshan stated.
"That means that the US action on the case was wrong in essence and they know this," she stressed, reminding that her family attorney also confirm her words.
"Therefore, Shahrzad's detention has been an illegal move and it is now three years that my daughter has been in jail for her attempt to buy a single pair of night-vision goggles," Rowshan explained.
Rowshan further noted the US prison guards' mistreatment of Shahrzad, and said whenever her daughter is allowed to contact the family from the jail, she complains about her jailors' physical and mental tortures and mistreatment.
In September Iranian Foreign Minister Manouchehr Mottaki said that Tehran has prepared a list of Iranian nationals who are in US jails for false charges, and added that he is closely pursuing the issue.
Speaking to reporters on the sidelines of the 65th session of the UN General Assembly, Mottaki said that the issue of the Iranian captives would be one of the main topics that he would discuss with the UN chief, Ban Ki-moon, during his visit to the UN headquarters.
Iranian President Mahmoud Ahmadinejad also said in September that the US has recently detained and held eight Iranian nationals illegally and based on false allegations.
President Ahmadinejad said in an interview with the Russian TV that the Iranian captives were arrested in third countries by US agents under "false accusations" and transferred here to US jails.
"This is abduction and does not fit in with any legal system. They (Iranians) had traveled to other countries with official visas but were arrested by Americans," Ahmadinejad stated at the time,
"Americans have not observed international law. They should review their conduct and allow the detainees to return home."
