A Saudi millionaire property developer has been cleared of raping a teenager after he claimed to have accidently tripped and fall on her.

Ehsan Abdulaziz, 46, was accused of forcing himself on an 18 year-old-girl who had slept on his sofa after a night out, reports UK daily Metro.

The businessman had already had physical relationship with the teenager's 24-year-old friend and said his penis might have been poking out of his underwear when he fell on the teen.

The young woman said she had woken up in the early hours of the morning, with Mr Abdulaziz on top of her, forcing himself on her.

He claimed he had gone to see if the young woman wanted a t-shirt to sleep in, or a taxi home. But he said she pulled him on top of her and started doing things.

His semen and DNA was found inside the young woman, but he said it was possible he had semen on his hands from having sex with the 24-year-old earlier.

The jury acquitted Abdulaziz of one count of rape after just 30 minutes of deliberations.

In his evidence, Abdulaziz demonstrated how the complainant had put her hand behind his head to pull her towards him, causing him to fall down.

During the trial Judge permitted the rare step of allowing 20 minutes of Abdulaziz’s evidence to be heard in private.

The women met the millionaire in London’s West End club, Cirque le Soir nightclub, where he invited them to his private table.
