A DOCUMENTARY about a mass murderer is set to be screened.

White House Farm: The New Evidence will be shown on Channel Five at 11.05pm today.

The show looks at how Jeremy Bamber was jailed in 1986 after being found guilty of the murders of his parents Nevill and June Bamber, his sister Sheila Caffell and her twin sons Daniel and Nicholas, who were only six-years-old, at the family farm in Tolleshunt D'Arcy.

The production company behind the new show is Title Role and the producer is Helen Tong.

The documentary looks at the events of the shootings, the trial and evidence Bamber insists was withheld at this trial.

Bamber is serving a whole life tariff but has consistently protested his innocence.
