A youth allegedly stabbed a tenth-grader after she refused his proposal of a relationship in Jhaudia Bazar area of the district town on Saturday afternoon.
Police, however, detained a man, who allegedly assisted the youth in stabbing her, from the area at night.
The victim girl, who has been undergoing treatment at a hospital, said one of the elder brothers of the locality named Ashraful Islam conveyed a message to her through a man to meet him at a restaurant after her tuition in the afternoon.
“I found Rana, who proposed to me, at the restaurant where the elder brother had also been earlier,” she said.
Rana locked into an altercation with her over the refusal of his proposal and stabbed her with sharp weapons when she finally cleared her stance about the relationship, the victim said from her hospital bed.
Dr Ashraful Alam, a residential medical officer of the hospital, said the body bore marks of injuries made by sharp weapons like blade or knife.
Annur Jayed, officer-in-charge of Kushtia Islami University Police Station, said they have already detained the accomplice Ashraful from the area.
Efforts are on to nab the main accused Rana and a process is underway to register a case, he added.
