Hena Akhter was sentenced to the whipping under Shariah law after being raped by an older relative when she left her house in rural Shariatpur a year ago, CNN reported Wednesday.
Shariah law is illegal in Bangladesh but it is still practiced.
Responding to public outcry over her death, a judge ordered Hena's body exhumed and a second autopsy revealed she died of internal bleeding from the imam-ordered whipping.
This week a court ruled doctors responsible for the first autopsy can be prosecuted for issuing a "false post-mortem report to hide the real cause of Hena's death."
Police are continuing to investigate and have arrested several people including the relative who raped Hena.
