A housewife was gang raped by three men at Paikpara village under Alamdanga upazila in Chuadanga early Monday.
Some of her in-laws have masterminded the incident, the victim alleged.
Meanwhile, police have arrested three of the in-laws for their involvement.
They, however, could not yet arrest the men who had raped her.
Detailing the incident, she said, three men whom she does not know picked up her and her husband from their house on Sunday night.
Then they tied up her husband in a field adjacent to their house and raped her by turns. As she returned home later in the morning, her in-laws warned her against disclosing the incident, she said.
Police, however, came to know about it upon information from the neighbours of the victim.
She was rescued and admitted to Sadar hospital, said Abu Zihad Fakhrul Alam Khan, officer-in-charge of Alamdanga Police Station.
Later the victim's father filed a case against three named and as many unnamed people in this connection.
