A CONVICTED robber set fire to her cell at a South Derbyshire women's prison.
Charlyne Newell torched books and clothing at Foston Hall on March 17 this year.
Derby Crown Court heard the incident left the room smoke damaged, but no-one was seriously hurt.
At the time of the offence Newell, of no fixed address, was serving a seven-year sentence for robbery.
She has since been transferred to Holloway Prison, in London, close to her family.
Newell was originally charged with arson with intent to recklessly endanger life – an offence she denied.
But when the lesser charge of arson was put to her, the 29-year-old pleaded guilty.
Gregor Purcell, defending Newell, said his client wished to have a pre-sentence report prepared before she was sentenced.
Recorder Michael Butterworth adjourned the case to the same court to September 4, for a report to be prepared before sentence is passed.
