The woman, identified as Yamuna Koli, surrendered before the police last night, following which she was arrested.
A police official said the woman was fed up with the torture by her husband Harischandra Koli (45) who was a heavy drinker.
The woman used to take small contracts for drying fish for earning a living.
The incident occurred on the night of October 21 when the woman realised that an advance of Rs 70,000 she had received for a contract was spent by her husband for liquor.
"Last night, she went to Alibaug Police Station and narrated the incident while surrendering herself," Senior Police Inspector Suresh Warade said, adding that further investigation is on.
