Sensible Sentencing Trust spokesman Garth McVicar said Couch had been finding it difficult to come to terms with the Parole Board's decision and feared his release. The board sought Couch's home and work addresses to include them in a list of places Tupe had to stay away from.
Couch, who was left with brain injuries after being bashed, has been fighting for justice for many years.
She is suing Corrections for $500,000 in damages, alleging Bell was not being supervised properly while on parole for previous aggravated robbery convictions at the time of the attack.
Tupe was sentenced to 12 years and will be released on conditions being monitored by Corrections, through the Probation Service.
