NOTORIOUS police killer Harry Roberts, who it is being widely reported is about to be released on parole, was moved from Sudbury jail after he made a woman's life a misery.
Roberts, who has served 48 years, of his life sentence, was in Sudbury in 2001 when he was granted leave to work at an animal sanctuary in north Derbyshire.
According to medial reports in 2009, the woman running the sanctuary and her son made a complaint about Roberts' behaviour when he worked there while on day release.
Their comments led to Roberts being denied parole and being moved to a closed prison, where he then allegedly began a five-year campaign of intimidation from behind bars against the 65-year-old woman.
She said Roberts, jailed in 1966 for gunning down and killing three officers in London, was still able to telephone her up to five times a week for nearly four years.
The Ministry of Justice revealed in 2009 that it had taken steps to ensure the family received more protection.
The spokesman said: "We have been working with the family and made considerable efforts to improve their situation. Procedures remain under constant review. Protecting the public is paramount."
Roberts has denied all the allegations made by James and Joan Cartwright, who ran the Derbyshire sanctuary.
Derbyshire police did not comment on the claims.
