He made no application for bail and was remanded in custody.

Ms Ross, 45, who is facing 15 charges made a release application, which was opposed by the Crown.

The defence said Ms Ross was supported in court by family and submitted she had strong ties to the community and had never previously spent time in custody.

Mr Stewart refused bail, saying he was not satisfied conditions proposed by the defence would ameliorate the bail concerns.

There were teary scenes as Ms Ross was led from the court.
