A nurse who filmed himself raping two unconscious female patients in the hospital where he worked has been jailed for 18 years in the UK.

Andrew Hutchinson assaulted the women who had been brought into the A&E department at Oxford's John Radcliffe Hospital after they had drunk too much on nights out.

He also recorded himself sexually assaulting two other unconscious drunk women while volunteering in the medical tent at a local music festival, a court heard.

The 29-year-old's victims were completely unaware of what he had done until detectives traced them.

His crimes came to light after he was arrested for voyeurism in November 2013 for illicitly filming young girls, including one aged just nine, at a leisure centre in Abingdon, Oxfordshire.

Police searched his home and found footage of the sex attacks on his phone and computer equipment.

Several of Hutchinson's victims were in court to see him jailed and some wept as his offences were described.

Judge Ian Pringle QC called Hutchinson's crimes "despicable" and ordered he should serve an extended licence period of seven years after he is released from prison.

The judge told him: "When they were unconscious requiring your help and your assistance as their nurse, you raped them and you filmed it.

"It is impossible to conceive of a greater breach of trust in our society than that."

Oxford Crown Court heard that hundreds of other voyeuristic pictures were found of women it had been impossible to trace, including "upskirt" shots taken on the Tube while Hutchinson was a volunteer at the 2012 Olympics.

At a hearing last month, Hutchinson, of Garford, near Abingdon, admitted 27 charges of rape, sexual assault, voyeurism, outraging public decency.

He also admitted making indecent images of children, theft of medical equipment and theft/possession of controlled class B drug ketamine.

Speaking outside court, Detective Chief Inspector Mark Johns of Thames Valley Police said: "I have no doubt that Hutchinson would have continued to offend had he not been arrested.

"So I am delighted that this prolific offender will now be behind bars for a significant period of his life.

"This has been a particularly complicated, unusual and sensitive case as the victims of his sex offences were not aware that offences took place because they were not conscious.

"Thames Valley Police sent specially-trained officers to personally speak to all the victims."
