He was found by the jury of all charges but cleared him of the charge of assault by penetration at the end of the trial yesterday.

Judge Freya Newberry said sentencing him, “If you formed a view that the woman wanted to have sex with you, you were very much mistaken.

“It was quite clear that you decided that you wanted to have sex with her and she had no recollection of what happened but you saw an opportunity. It was a mixture of your own desire and arrogance regardless of any intoxication on your part.”

The accused was found guilty of carrying the woman over his shoulder after she was denied entry into a nightclub in central London for being drunk and raping her in an alleyway.

On March 11 last year, The court heard that the 18-year-old victim had been out for the night at a bar in London Bridge area before being asked to leave as she had too much to drink.

The 28 year old had been outside the bar, he saw the victim and began talking to her. The CCTV footage showed them chatting, Naker appearing to show her concern, picking her up when she fell and offering her his jacket. He gave her a piggyback, at one point.

She pushed him off, when he then tried to kiss her. Naker who kept on trying to pull her in the opposite direction to where she was walking and eventually succeeded, dragging her to a secluded corner. The jury was told that he raped her and sexually assaulted her multiple times there.

After seeing, suspicious activity on the CCTV, security staff working nearby went to investigate. Naker told them he had met the woman in a club nearby and he gave them his details and then left.

The staff had found the woman unconscious on the ground with her underwear pulled down and called an ambulance, it emerged during the trial . She was taken to hospital to recover and later taken to a crisis centre, where it was determined she had been raped.

The next day,he was arrested. He claimed the victim had asked him for sex but was charged with rape in November last year, during his police interview.

The police was told by him that, the sex was consensual and said the woman had not appeared drunk. He admitted later searching online for a definition of the word “rape” but said it reassured him he had done nothing wrong.

Detective Constable Aidan Kersley from Scotland Yard’s Child Abuse and Sexual Offences Command, said: “Naker deliberately targeted his victim as someone intoxicated and vulnerable. After talking to her for a matter of minutes, he managed to drag her to a secluded area where he raped her.

“She has no memory of what happened. Naker then brazenly gave security guards his name, confident that the victim’s intoxication would protect him.”

However, the Metropolitan Police said its investigation was able to prove the woman had been raped and build a strong case against him because “the simple fact was, she was too drunk to give her consent”.

Kersley added, “This case shows that no matter what the circumstances, we will work tirelessly to bring rapists and sexual offenders to justice. Anyone who sadly finds themselves in similar circumstances should take courage from this case and the conviction we have seen today. Our officers are experienced, highly trained and treat victims with the sensitivity and compassion they deserve.”
