A schoolgirl was killed after gang-rape at Kalabagan in the capital Thursday noon.
The deceased has been identified as Anushka Amin Arna, daughter of Al Amin.
The body of the ill-fated girl was sent to Dhaka Medical College and Hospital for autopsy.
Kalabagan police arrested four rapists immediately after the incident, taking them in the custody.
Mohammad Sharif, brother-in-law of the deceased, told the Daily Sun that Anushka, an O level student of Mastermind School, was going to a coaching centre from her residence at Kalabagan at noon.
At that time, one of her girl friends called her and took to Dolphin Lane.
The prime culprit Fardin and his three friends forcibly took her to a residence and raped her one after another, he said.
Seeing her condition serious, the four fled.
Local people took her to Anwer Khan Modern Medical College Hospital where the doctors declared her dead, said Sharif.
