Grace Mugabe PhD: Arrest made over corruption allegations
The vice chancellor of the University of Zimbabwe has been arrested in connection with an investigation into the awarding of a doctorate to former first lady Grace Mugabe.
Mrs Mugabe was awarded a PhD just months after enrolling in 2014, despite it usually taking years to complete.
Members of the sociology department said they had not seen supporting evidence, and called for the nullification of her qualification and a full investigation.
The document was only published online in January this year, four years after she graduated, and has been the subject of intense speculation since.
In November Robert Mugabe was ousted from office after 37 years of rule amid growing speculation his wife was lining herself up to replace her aging husband in power.
