A 14-year-old girl has been raped and killed allegedly by six people in Narayanganj.
The deceased is Munmun Akter, a third grader, who was the younger daughter of one Majnu Mia from the district.
The prime accused, Rasel Mia, 25, a trawler driver from the same area, confessed to having committed the crime before the court of Narayanganj's Senior Judicial Magistrate Ahmed Humayun Kabir on Sunday.
Siddhirganj police station's Sub-Inspector Aminul Islam said they arrested Rasel and his friend Nesar Ali over the alleged rape-murder after a case was filed.
Quoting Rasel, Aminul, also the investigation officer, said he had claimed to have developed a love affair with Munmun recently, and used to take her on his trawler very often.
Colluding with Rasel, Nesar tricked her into such a trip on April 17. The six friends raped the girl in turns in the middle of the river, the SI continued.
As she became unconscious, the rapists strangled Munmun to death and threw her body into the river, which was recovered the following afternoon, he added.
Nesar was put on a four-day remand. The rest accused are on the run.
