They were joined in their depraved torture of the woman by Alexander Azevedo, 21, in whose flat the ordeal took place on June 21 last year, and then 16-year-old Argest Sallaj – who can now be named after the judge lifted a reporting restriction that had banned his identification.

After hours of on-off abuse, which saw Washington, Weir and Azevedo force the woman to smoke heroin, the couple disappeared to have sex in a bedroom while Azevedo raped her in the living room.

Their romp complete, Washington and Weir tied her to a chair then beat her until she was badly bruised. Azevedo then sent her home in a taxi.

Jailing the gang for a total of 35 years at Oxford Crown Court this afternoon, Judge Nigel Daly said: “This all went on for something like 12 to 16 hours. She was totally abused, humiliated and tortured. It included as I say, forcing her to take heroin and eventually being raped.

“Had I not heard the evidence I do not think I would have believed this sort of thing could have happened between so-called friends and acquaintances.

“I was shocked not only by the events covered by this indictment but by the lifestyle that you described, the lifestyle you were leading, as if it was in some way normal.

“None of you were over 20 years. You seem to have descended into a life of drug-fuelled debauchery, displaying a total lack of morality or self-control.”

Summarising the night of torture at Friday’s sentencing hearing, prosecutor Patrick Duffy said: “This is a brutal set of offences.

“These four defendants initiated a campaign of violence and threats against the complainant, inducing in her a state of terror as they falsely imprisoned her, abused her, assaulted her and [in the case of Azevedo] raped her.”

Washington lured her to the flat on the false pretence of a party, the prosecutor said.

She was held against her will in Azevedo’s flat for 12 to 16 hours. Weir locked the doors and told the victim: “No one is leaving.”

Washington began the ordeal by branding her a ‘pig’ and a ‘snitch’, while love-interest Weir rang Sallaj and told him to come over and ‘beat the s*** out of this girl’ before telling the victim to ‘shut the f*** up or I’ll stab you’.

That threat was followed up later with Weir holding a knife to her face and demanding to know where she wanted to be cut. “You will be scarred for the rest of your life,” he told her.

Over the evening, she was made to drink chilli sauce and the contents of a bottle of water used as an ashtray.

Cigarettes were stubbed on her skin, she was made to eat garlic granules, beaten with a hairbrush and vacuum cleaner parts, and had pliers applied to her tongue by Washington and Azevedo.

Sallaj ‘booted’ her as she was on the ground being forced to clean up. The youngster also spat at her and scrubbed her skin using a dishcloth scourer pad.

The young victim was made to stand in the shower while the defendants switched between hot-and-cold water. Her hair was cut by Weir using a knife then, later, by Washington using scissors.

She feared that she would be killed and her body dumped in the woods. Sallaj said they could ‘get a van’ and ‘take her out to the woods and kill her’. Washington suggested they could ‘leave her in a tent in the woods’.

Mr Duffy said the evidence implied that Sallaj wanted to see the woman’s semi-naked torso, asking her to remove her arms from where they were crossed over her chest. “He [Sallaj] told you to move your arms. F***ing move your arms and listen to him,” Weir told the victim.

Having taken drugs before she visited the flat and taken cocaine at points during the evening, her nose was held and she was forced to smoke heroin by the three older participants and Weir made her take Valium.

It followed Weir telling her: “Crack head? I’ll show you a crack head.” The victim was filmed singing a song about her being a ‘crack head’ and the footage uploaded to her Snapchat.

Later, Washington and Weir disappeared to a bedroom to have sex. Left alone with the victim, Azevedo raped her the sofa then told her to clean herself up when he had finished.

Washington and Weir returned from the bedroom, tied the victim to a chair and beat her.

Rapist Azevedo put her in a taxi and sent her home, where her shocked mum saw her and took her to A&E after speaking to her in the kitchen.

When the woman arrived at hospital the police were called. She told detectives in a video-recorded interview played to jurors at the trial I February: “I genuinely thought I was never going to see my family again. I was thinking, well, no one’s going to know I’m here, my family don’t know I’m here. No one’s ever going to find me or know what happened to me.”

Weir, whose previous convictions included conspiracy to supply drugs, was also sentenced on Friday for a single count of being concerned in an offer to supply class B drugs. He was stopped inthe company with another young man at Bournemouth Railway Station on October 27, 2020. The pair had £500 in cash and a ‘burner’ phone containing messages linking them to drug supply.

Sallaj was acquitted of the two most serious counts that he faced – allegations of urinating on her and pouring boiling water on her shod foot. He asked the judge to pass a sentence that would spare him an immediate spell in custody, saying the community would ‘probably be safer’ if he were kept out of prison.

Azevedo, of Britannia Wharf, Banbury, was convicted of rape, false imprisonment, administering heroin and ABH. He was found not guilty of one count of ABH and administering Valium. He was jailed for 15 years.

Weir, of Pope Walk, Banbury, was cleared making a threat to kill and one ABH count but convicted of administering a noxious substance with intent, false imprisonment and ABH. He received nine-and-a-half years, including a six month sentence for dealing drugs in Bournemouth.

Washington, of no fixed address, was convicted of false imprisonment, ABH and administering heroin but acquitted of administering Valium with intent. She was jailed for eight years

Sallaj, 17, who can be named after the judge lifted reporting restrictions, was convicted of false imprisonment, ABH, common assault and battery. He was cleared of pouring hot water on her foot and urinating over her. He was sentenced to three years in a young offenders’ institution.
