Belinda Johns is a former inmate of Wentworth Detention Centre.
Belinda was a blind woman imprisoned at Wentworth Detention Centre for possession of illegal firearms, who immediately takes an interest in Sonia Stevens. It transpires that she deliberately had herself imprisoned to get even with Sonia Stevens for the incident that took away her sight.
She is responsible for the series of accidents and assaults that befall Sonia: mixing ground glass into her hand cream (417), stabbing her in the back with a fragment of mirror (420), and strangling her with a kettle flex (425).
When she has Sonia cornered in the dark in the library, she finds she cannot manage to deliver the coup de grace with a wrench she has hidden among the bookshelves and is transferred to D Block.
