Ismael Omer, 32, preyed on the “clearly drunk” woman who had missed her last bus home.
Omer took her to his home in Notting Hill, West London, and raped her in a cramped basement, Southwark crown court was told.
When she fled and pressed charges he tried to exploit her memory loss and claimed she had made advances towards him.
But CCTV footage of the “vulnerable” complainant stumbling past a Ladbrokes betting shop and a McDonalds near his house revealed she wasn’t initiating any sexual activity.
He wept in the dock and hung his head in shame as he was jailed for five years at Southwark Crown Court.
Omer claimed asylum in the UK after being tortured by Saddam Hussain’s Baathist regime and cannot return because his hometown is now controlled by Islamic State fighters.
He denied the charge but was convicted of one count of rape following a trial at Southwark Crown Court.
