Tehran prosecutor Abbas Jafari Dowlatabadi said Movahedi would remain in jail until a court decides on an alternative punishment and said Bahrami has sought financial compensation from her attacker for the cost of treating her injuries.

Bahrami said that international attention to her case was also a factor in her decision to pardon him. She said "It seemed like the entire world was waiting to see what would happen". Amnesty International had urged Bahrami to pardon him but are appalled that a member of the medical profession would deliberately blind another in the name of the law.

Bahrami, who has an electronics degree and worked in a medical engineering company before the attack, moved to Spain with the help of the Iranian government where she has undergone a series of unsuccessful operations. She has recently published a book in Germany Eye for an Eye, based on her personal life and her suffering since she was blinded.

There have been several other acid attacks of women in Iran. Last week, a young woman died when a man poured acid on her face after she rejected his marriage proposal. As yet, her attacker has still not been found.
