The duo allegedly caught her and asked her to have sex with them. When she refused, they threw acid on her.
The woman was visiting her parents in the village. Based on her statement, two men - Khokhan and Swapan - have been named as the attackers.
According to the woman's family members, the duo had been trying to have sex with her before she got married.
In a similar incident, a girl was attacked with acid in Dhanbad.
