MASS murderer Jeremy Bamber has declared he will sue the author and publishers of a book which details the events of the night when he slaughtered his family.

Nearly 2.5 million viewers saw the Real Crimes documentary, based on the book of the same name, late on Monday night in which the surviving relatives described their fears for their safety should he ever walk free.

Bamber is serving five life sentences for killing his adoptive family at their home in one of East Anglia's most notorious crimes.

In the documentary , his cousin Ann Eaton said that if the murderer was ever released, she feared he would pick the family off "one by one".

Mrs Eaton now lives in White House Farm, Tolleshunt D'arcy, where the killing spree took place on August 7, 1985.

Bamber murdered his adoptive parents, June and Nevill, their daughter, Sheila Caffell and her six-year-old sons Nicholas and Daniel.

The killer, who has been told by the Government that he will never be released, has always protested his innocence and has a website detailing what he believes are flaws in the original investigation.

He has already issued a libel action against Mrs Eaton claiming that her comments in the documentary about being picked off were "evil minded and injurious".

Bamber claims the statements could have profound consequences for his security classification as a prisoner and chances of parole.

A statement on his official website also declares he will sue Shari-Jayne Boda, the author of Real Crimes, and the book's publisher Granada Media.

Last year the EADT revealed how Bamber was taking members of his adoptive family to the High Court in a bid to claim half of his grandmother Mabel Speakman's will which he was cut from before her death.

Bamber's solicitors were not available for comment last night.
