A 19-year-old boy was arrested after he allegedly raped his nine-year-old stepsister in Soweto, Johannesburg police said on Wednesday.

Inspector Kay Makhubele said the boy and his sister were at home alone on Tuesday night when the alleged rape occurred.

"It is alleged that the boy raped his stepsister in her bedroom. When her parents got home she told them what happened and they reported it to the police.

"The boy was only arrested on Wednesday morning," he said.

The boy was expected to appear soon in the Protea Magistrate's Court on a charge of rape.
