A woman with learning difficulties was held hostage and tortured during a horrific six-and-a-half-hour ordeal filmed by two women and a teenager.

The victim was repeatedly sexually assaulted, forced to eat glass and excrement, and had bleach and boiling water poured over her after being kidnapped and taken to a bungalow in a quiet village cul-de-sac.

Elisha Robinson and Jodie Colvin, both 23, have been jailed for 12 years and nine months each over the sadistic attack.

A 17-year-old, who was 16 at the time and cannot be named for legal reasons, has been sentenced to six years in youth detention.  

Norwich Crown Court was told the women had been high on cocaine and had sent chat messages during the torture, egging each other on to subject their victim to ever more extreme and degrading acts.

They also filmed each other torturing her and later searched the internet for ways to kill her and dispose of her body.

Judge Andrew Shaw said the victim had been “absolutely terrified” throughout the ordeal and that footage shown during a trial had been “horrific viewing” for those forced to watch it in court.

The 21-year-old victim, who is extremely vulnerable with significant learning difficulties, was taken to hospital following the attack and has suffered serious lasting physical and psychological effects, he added.

The court was told that the trio had been persecuting her over a friendship she had with a 15-year-old.

After arranging to meet her at a cinema in Norwich on February 6 the victim was persuaded to get into a car and was taken to Colvin’s home at Sterlet Grove in Mulbarton.

The gang exchanged messages in which they discussed “knocking her teeth out” and “tying her to a chair and beating her”.

Over the next six and a half hours she was punched, kicked, cut, and was violently sexually assaulted using a beer bottle.

Messages exchanged between her attackers included one saying it would be “fun” to release her and then track her down and beat her further.

They also mocked their victim that she had “got off easy” and they wanted to get acid to pour over her.  

In a statement read out on behalf of the victim in court, she said: “I really struggle to get my head around how a human being could treat another human being the way I was treated. And why did it happen to me?

“I can barely sleep as I keep reliving the whole thing and if I do sleep, I wake up terrified from recurring nightmares.

“The knock-on-effect of the assault and the damage it has caused to myself, and my family, will last forever. Nothing will ever be the same again.”

Colvin and Robinson eventually “marched her out of the house” with a baseball bat and threatened they would kill her mother, brother and dog if she reported the attack. 

The court was told the shocking attack occurred despite other young children being in the property at the time.

Robinson, from Attleborough, and Colvin pleaded guilty to offences including sexual assault, false imprisonment, grievous bodily harm and administration of noxious substances. 

Their teenage accomplice admitted false imprisonment and GBH but denied sexual assault. But he was found guilty following a trial during which the victim was forced to relive her ordeal. 

Sentencing him to youth detention, Judge Shaw told him although he had been young and had not actively hurt the victim himself he had been involved in the plan to “trap her and encourage as much pain as possible”.

He said Robinson and Colvin had shown remorse but had no mitigation other than having pleaded guilty.

Describing it as “amongst the most serious, unpleasant I have ever dealt with” he told them it was a “terrible, terrifying and horrific attack”.

“How you could have treated another human like this is beyond belief,” he added. 

He ordered they serve at least two thirds of their sentences in jail.

Judge Shaw also praised the actions of a local couple who cared for the victim after she sought help at a nearby house.

He recommended they receive a £500 reward from the High Sheriff of Norwich.

Detective Sergeant Tom Cole, who led the investigation, said: “This was a horrific, calculated and vicious attack over a number of hours.

“The three defendants subjected her to a hugely traumatic event and none of us can imagine how truly awful that experience must have been for her.

“I want to thank her for showing such courage and bravery to tell us what they had done to her. I hope this sentence provides some closure and some justice. “
