While the woman's 20-year-old husband and one of his elder brother were arrested on May 24 from the house in Abhlod village where the incident took place, two others are absconding, a police official said.
The crime was allegedly committed by the elder brothers of the victim's husband, who, having a dispute with his wife, "wanted to settle the scores" with her, Dahod rural police station sub-inspector N K Desai told PTI.
The woman had gone to her parents' house in Gadoi village on May 20 and was forcibly brought back to her husband's house. Her family members later lodged a complaint with the local police that she was kidnapped.
The officer said the couple was married for a year.
