A form three student in Dodoma has been arrested by police on suspicion of violently robbing his mother and raping her.
The police commander in the area, Gilles Muroto, said the boy is a hardened criminal and recently raped his mother.
"The woman did not know that the thief was her son, but the young man knew that he was raping his mother," said Muroto.
He said the student narrated how he had raped his mother when he was questioned by the police.
When asked by Muroto Commander in front of journalists why he was involved in crime rather than study, the boy said he was influenced by the difficult life he lived.
"I live with my mother alone, so I have no one to fend for me. I have no money for school shoes, notebooks, books, school uniforms and other needs. That's why I steal people so I can get it," said Mohamed.
He said his father had died a while ago.
