Dhaka: A teenaged school girl in Bangladesh was allegedly burnt to death by her principal for reporting a sexual harassment case against him, triggering nationwide protests in the country. Nusrat Jahan Rafi, 18, was set on fire at her school (madrasa) on April 6 by four burqa-clad assailants few days after she complained against principal Siraj-ud-Daula for inappropriately touching her after calling her in his office.

Siraj is one of the 17 people arrested in connection with the case. Rafi succumbed to the injuries on April 10. Her death led to protests across Bangladesh with people on Thursday forming human chains and holding demonstrations seeking justice for the victim. The demonstration sought stern punishment for the victim's murderers and expressed condolences to her bereaved family, the Dhaka Tribune reported. Online news portal bdnews24.com quoted police as saying that Siraj orchestrated the killing of Rafi from jail after his arrest on March 27 in the case. Deputy Inspector General Ruhul Amin, who is heading the probe committee, said the investigation will take several more days to wrap up as investigators are examining various documents.
