A Bristol woman will appear in court charged with helping a convicted killer escape from prison.
The 34-year-old is alleged to have assisted murderer Brian Grady, 26, who is also known as Brian Revill, in his escape from HMP Prescoed in south Wales on Monday.
She will appear at Caerphilly Magistrates Court. A 37-year-old man from Bristol who was also arrested on suspicion of helping the escape has been released without charge, Gwent Police said.
Grady remains at large and police believe he could be in the Bristol area, where he has contacts.
Grady, of Barton Hill, Bristol, was jailed for a minimum of 11 years in July 2003 after being convicted of murdering "good Samaritan" Liam Attwell in the Canon's Marsh area of the city.
Mr Attwell was stabbed in the heart when he confronted a group of youngsters trying to rob three teenage boys of a mobile phone.
