The British headteacher convicted of stealing £500,000 from her school has been remanded in custody after failing to appear before a judge to be sentenced.
Former nun Colleen McCabe, 50, who used the money to fund a lavish lifestyle, shook her head in disbelief after being told she would not be allowed her freedom.
McCabe failed to turn up for sentencing on Friday - and never intended to, Greenwich Magistrates Court heard.
Reading from medical reports, District Judge Michael Kelly said McCabe had already told her psychiatrist she would not turn up for sentencing.
He added that she overslept yesterday when she should have been at Southwark Crown Court to face a "substantial" jail sentence.
McCabe was convicted of theft after an audit at St John Rigby College, a 1,100 pupil state-funded Roman Catholic school in West Wickham, south-east London.
After she failed to appear in court she was taken from her home in Sidcup, south-east London, by ambulance, to Queen Elizabeth Hospital, Woolwich.
She was then arrested on Friday evening and spent last night in cells at Plumstead police station in south London.
Judge Michael Kelly refused bail, remanding McCabe in custody until next Tuesday, after hearing submissions from the prosecution and the defendant's solicitor.
He said: "It is clear you have failed to answer bail before the crown court."
He added: "Also I have real concerns about your welfare and mental health, given what I have read in the report, and given the opportunity you may well harm yourself, so in these circumstances it seems to me right you will be remanded in custody to go before the crown court on Tuesday."
