The brutal incident became known yesterday when the victim's father Tayab Ali, a small businessman in the town, lodged a case with the Natore Sadar Police Station accusing BNP cadres Maruf, Sohel and five unnamed.

The victim had an affair with BNP activist Mithu, locals said.

The BNP cadres (Mithu's friends) wearing 'burka' (veil) went to the school gate in a microbus on that day and called her out saying that Mithu was waiting for her.

When she came out at noon, they dragged her onto the microbus and sped away.

After taking her to an unknown place, Maruf proposed to marry her that she rejected.

At night they made her drink and at one stage, they all raped her one after another.

As she fainted, they dropped her in a ditch beside a road near Natore City College at dead of night.

The victim's family members recovered her from there the following day and provided her treatment at home.

As the victim's father was preparing to file a case, local Ward Commissioner Sajjad Hossain Sohag, who is affiliated with local BNP's youth front Jatiyatabadi Jubo Dal, threatened him with dire consequences if any case is filed for the incident.

He offered the family Tk 20,000 for not filing a case.

He is also learnt to have told his friends that he collected about Tk 90,000 from the rapists to cover the incident.

The family denied the offer but did not file any case for fear of harassment.

Local journalists came to know the matter and informed the police who after investigation recorded the case.

Mithu and the alleged rapists were absconding till filing of this report.

The incident has created anxiety among local people.
