The duo are Selim, 35, son of Tota Mia, and Azizul, 36, son of Ali Rahman, of the same village.
Shah Md Monzur Kader, officer-in-charge of Sonargaon police, said: “The victim and his brother-in-law went to their relative's house at Mundirpur village on Thursday afternoon.
“Seven to eight youths led by Selim abducted her around midnight as she went outside the house to go to the toilet and took her to a nearby orchard.”
Her brother-in-law chased the attackers but was caught and tied to a tree. “Then she was gang-raped throughout the night in front of her brother-in-law,” the OC told the Dhaka Tribune.
The rapists tried to suppress the incident by managing arbitrator Anwar and Manju as the locals learnt about it Friday morning. The duo were supposed to hold a hearing around 3pm yesterday. But getting no justice, the victim went to the police station and filed a case against eight people including Selim, Azizul, Dalim and Alam.
Several teams of the police conducted raids in Mundirpur area around 5:30pm and arrested prime accused Selim and Azizul.
The victim was sent to Narayanganj General Hospital for medical test, said police.
