The Tony Martin case caused a massive public outcry

Mr Martin, 49, of Emneth Hungate, Norfolk, told BBC Radio Five Live on Sunday that he might "put the record straight" when he retired.

"I may write a book," he said. "At a later date when I have got a little bit more time."

Mr Martin was dismissive of a new book written about him by reformed criminal John McVicar.

He said "A Right To Kill?", which went on sale last week, was "highly malicious".

But he said he would not sue Mr McVicar, who served 11 years in prison for armed robbery and was once described as Britain's most wanted criminal before becoming an author, over the book.

Brendan Fearon was seriously injured in the shooting

"You rise above these things," said Mr Martin. "It just dies away and it is a flutter for the day."

Mr Martin said he had not co-operated with the McVicar book nor benefited from it financially.

The farmer killed Fred Barras in August 1990 and wounded the teenager's accomplice Brendan Fearon after confronting them at his isolated home.

Both burglars had driven from their home in Newark, Nottinghamshire, to raid Mr Martin's home.

Mr Martin was initially convicted of murder and given a life sentence.

The conviction was reduced to manslaughter on appeal and the sentence cut to five years.

Mr Martin was freed from jail in July.
