Hertfordshire rapist Robert Atkinson filmed abuse of woman
A man who filmed his violent abuse of a woman has been convicted of six charges of rape.
Robert Atkinson, 41, of Cleves Road, Hemel Hempstead, recorded the sex acts, which followed "physical violence", St Albans Crown Court heard.
As part of the trial the jury had to watch 90 minutes of home-made videos.
Judge Andrew Bright QC, remanding Atkinson in custody until sentencing on 3 October, warned him he faced a "very, very substantial prison sentence".
The public gallery at the court was cleared while the jury viewed the videos.
Prosecutor Isabel Delamere said the victim complained to the police late last year and Atkinson was arrested on 20 December.
When questioned by detectives, he blamed the woman's friends for putting her up to it.
Atkinson was found guilty of six charges of rape, attempted rape and two charges of causing actual bodily harm. He was found not guilty of another charge of assault by beating and voyeurism.
He was cleared of a charge of common assault on the direction of the judge.
The judge thanked the jury for their work on the case, saying: "You had to watch one-and-a-half hours' worth of videos you wish you did not have to watch."
