A HEAD who failed to appear in court after being convicted of stealing pound;500,000 from her school has been arrested and remanded in custody, and is due to be sentenced on Monday. Former nun Colleen McCabe, who went on a pound;500,000 shopping spree with money stolen from St John Rigby college in east London, failed to turn up for sentencing last week after being admitted to hospital with chest pains. McCabe, 50, was arrested on Tuesday after failing to produce a valid medical certificate.
