"A woman today filed a complaint of rape against her husband's advocate in Kadi taluka police station in Mehsana district," police inspector S L Karan told PTI.
The woman alleged in her complaint that the advocate raped her many times over last three years by "luring her with an offer that only he can save her husband from languishing in jail," he said.
The advocate, identified as Jignesh Mewada, practicing at Gandhinagar district court, is absconding.
The woman's husband was one of the co-accused in a gang rape case involving a student at an educational institute in Patan district in 2008.
A special trial court had found him guilty of rape and conspiracy and sentenced him to life imprisonment in 2009.
The convicted persons had challenged the verdict before Gujarat High Court, but failed to get any relief as the high court has upheld the lower court order.
