A 17-year-old girl was raped and murdered at a flat in the city's Kalabagan area yesterday, her mother has alleged.
Police said the victim, an O-level student of an English medium school in Dhanmondi, was brought dead at Anwar Khan Modern Hospital in the afternoon.
A youth, who took her to the hospital, was detained in connection with the incident. The detainee has recently passed his A-level examinations, said the law enforcers.
Abul Hasan, assistant commissioner (New Market Zone) of Dhaka Metropolitan Police, said the incident happened at the youth's home in Dolphin Goli of Kalabagan. His mother and two brothers were away and his father, a retired government employee, lives in Rajshahi.
"We seized evidence, including bloodstained items and swabs, from the spot … ," the police official said.
Three friends of the youth, who went to the hospital, were also held for questioning.
The victim's mother alleged that her daughter was raped, tortured and killed by four youths, including the one who took her to the hospital.
She claimed that her daughter bled profusely and that she saw injury marks on her hands. "My daughter was killed as the culprits thought she would tell everyone what they did to her," she said.
The woman said her daughter went out yesterday morning telling her that she was going to one of her friends' home to bring some worksheets provided by a coaching centre.
Around 1:00pm, one of the youths called her over phone and told her that her daughter suddenly fell sick and that he was taking her to the hospital.
The mother saw the body after arriving at the hospital.
She claimed that the detainee took the body to the hospital since they had no way to hide it. "My daughter did not go to the flat willingly, she was tricked into going there," she said.
Assistant Commissioner Abdul said the duty doctor at the hospital informed them that the girl was brought dead. Kalabagan police later sent the body to Dhaka Medical College for autopsy.
"We didn't see any injury marks on the body," he said, adding the cause of death would be known after autopsy. "We're investigating the matter. Whoever is guilty will be brought to book," he added.
