The lawyer was summoned for questioning at Tehran`s Evin prison on Saturday.
Cairo: Amnesty International says the lawyer defending a woman sentenced to death by stoning has apparently gone missing, and two of his relatives have been detained.
Tehran said earlier this month that it would not carry out the stoning against Sakineh Mohammadi Ashtiani for the time being, but the mother of two could still face execution by hanging.
She has been convicted of adultery and other offences.
The London-based rights group says the lawyer, Mohammad Mostafaei, was summoned for questioning at Tehran`s Evin prison on Saturday, released, then asked to return. Amnesty says it`s not known whether he complied but he hasn`t been seen since.
Yesterday’s statement says Mostafaei`s wife and her brother also have been detained by Iranian authorities.
