Umme Habiba Rumi, 18, a second year student of Nazirhat College and daughter of Abul Kashem, committed suicide at her residence to avoid torments by Mohammad Azam and his brother Mohammad Nazim.

Azam and Nazim, both sons of Kabir Ahmad, used to hurl abuses at Rumi on her way to college for a long time, locals said.

Rumi's mother Monwara Begum asked Abdus Salam Talukdar, local union parishad chairman, to look into the matter and bring the brothers to task, relatives said.

At a salish (arbitration) on Thursday noon, Talukdar gave a 'token' punishment to them who took oath never to repeat their acts, police said.

But the next day while she was going to a relative's house, Azam pulled and tore her clothes a few yards from their house, witnesses said.

She did manage an escape, but half an hour later relatives found her body hanging from the ceiling of a room.

Rumi's mother Monwara Begum filed a case accusing Azam and Nazim.

The accused are absconding since the incident, police said.
