The woman, around 20 years of age and hailing from Jaunpur in Uttar Pradesh, got married in May this year.
The couple had come to live with the husband's father, a powerloom worker, at Mithpada chawl in Bhiwandi about a week back, Nizampura assistant police inspector Tilani Sayyed said.
When the couple was asleep in the wee hours yesterday, the three men barged into their house at around 1 AM and beat them up.
The three accused, around 25-30 years of age, then forcibly took the woman's husband outside the house and later gangraped her, he said.
Offences have been registered under sections 376(d) (rape), 452 (house-trespass after preparation for hurt, assault or wrongful restraint) and 394 (voluntarily causing hurt in committing robbery) of the IPC, the API said, adding that a manhunt has been launched to nab the culprits.
