A 23-year-old man appeared in the Mansa Magistrate Court.
Bright Chungu was accused of incest contrary to section 159(1) Chapter 87 of the Laws of Zambia.
The man allegedly started an intimate relationship with his 13-year-old sister.
It is also reported that on the same day Chungu grabbed his sister and dragged her into the bush where he allegedly raped her and threatened to kill if she told someone about the incident.
The victim later told her mother and reported Chungu to the members of CCPU.
Magistrate Makalicha said he had no jurisdiction to sentence the criminal and committed him to the High Court.
