(CNN) A court in Bangladesh has sentenced 16 people to death for the murder of a teenager who was set on fire after she reported sexual harassment.

The ruling in southeast Bangladesh's Feni district, about 100 miles southeast from the capital Dhaka, comes six months after 19-year-old Nusrat Jahan Rafi was killed.

Rafi had filed a sexual harassment complaint with local police and named her school principal, Siraj Ud Doula, as one of the accused.

Police spokesman Banaj Kumar Muzumdar said Doula then contracted several people to kill the teenager -- and ordered the perpetrators to make her death look like a suicide.

Members of the Transparency International Bangladesh group stand in a human chain during a protest in Dhaka on April 21, 2019, following Nusrat Jahan Rafi's murder.

On April 6, Rafi was lured out of her school classroom and onto the roof, where a group of men wearing burqas gagged and restrained her. They drenched her in kerosene and set her on fire, Muzumdar said in May.
