That was the last time I saw my neighbour," she said.Olala-Maguvu said whenever she closes her eyes, she sees Mashilo being swept away."I can't sleep and can't stop thinking about Mashilo.

I am calling for calm and for police to be given an opportunity to do their work."Police spokesperson Captain Raymond Sebonyane said a missing person's file was opened and the search continued.
