However, the Iraqi man’s victim was captured on CCTV “clearly drunk” on August 27 last year.
A court heard how Omer persuaded the “naive” victim she was safe with him and took her to his nearby home in Holland Park Avenue, Notting Hill.
The victim said she realised “something was wrong” but she was powerless to stop the attack once he pounced on her in his cramped room – said to be “little more than a cupboard”.
Omer refused to accept he raped her claiming the woman had come onto him but the court saw the footage of his victim stumbling past a Ladbrokes betting shop and a McDonalds near his house revealing she wasn’t capable of initiating sexual activity.
Omer claimed asylum in the UK after being tortured by Saddam Hussain’s Baathist regime and can’t return because his hometown is now controlled by Islamic State fighters.
Judge Martin Beddoe said: “On that evening in August last year you came across a very drunk, rather naive, and thus vulnerable young lady who was lost, who had lost her mobile phone and because of that circumstance and because of her condition could not find her way or get back to where she really wanted to be.
“I’m in no doubt that she didn’t come on to you as you falsely described in your evidence and she didn’t then make sexual overtures towards you.
“You have exploited her memory loss to try and portray her as the initiator of the sexual activity that subsequently resulted between you.
“The sex is the only sex there was and which she tried to persuade you not to perform.”
Omer, of Seymour Place, Marylebone, west London, must sign the Sex Offenders’ Register for ten years.
“The sentence handed to him reflects the gravity of the offence and the effect it has had on the victim’s life.”
He was convicted of one count of rape following a trial at Southwark Crown Court.
Omer was jailed for five years.
