A teenager and the mother of another teenager have been arrested over the rape of a grade II student at Naria Upazila in Shariatpur.
Police arrested them after the victim's mother filed a case Sunday morning.
The child aged around seven has been undergoing treatment at Dhaka Medical College.
She was first admitted to Shariatpur Sadar Hospital with critical injuries Saturday evening. Dr Ambia Alam Kona, gynaecologist at the hospital, said that the child had been moved to the DMCH because of excessive bleeding.
The two teenagers, aged 13 and 14, picked up the victim when she was playing with her friends after school and raped her at a nearby place. She was later rescued by her classmates.
Upazila Nirbahi Officer Shanjida Yasmin has assured all kinds of support for the treatment of the child and legal proceedings.
