CCTV captures the moments before a lurking rapist is captured by police after he subjected her to a horrific two-and-a-half hour ordeal.
Diljeet Grewal, 28, of Windsor Gardens, Hayes, was sentenced to 15 years in jail after raping and robbing the woman by knifepoint.
He met his victim in a pre-arranged meeting at a property in Hillingdon in April. Shortly after arriving, he produced a knife and threatened the woman, causing her to fear for her life.
He then carried out a sustained attack which lasted for approximately two-and-a-half hours.
Once he finished physically attacking the woman, Grewal stole her phone and threatened her again, this time demanding money.
She handed him cash from her handbag but he continued to ransack her room looking for more money, before fleeing the building.
After Grewal left, the woman was able to call a friend who was outside the UK, who in turn contacted police.
Officers attended and upon arrival found Grewal "lurking" outside the address. He matched the description of the suspect and when spoken to, he identified himself. He was arrested immediately.
Grewal, who had previously been charged with rape and aggravated burglary, was sentenced to 15 years - with a further five years on licence upon release - at Isleworth Crown Court on Friday.
Det Con Mark Palmer, who led the investigation, said on Saturday: “I welcome this sentencing and hope it gives the victim some measure of closure.
“I would like to thank the victim for her bravery in supporting our investigation and identifying Grewal as her attacker.
“I also hope it encourages any victims of sexual assault, to come forward and trust that officers will treat crimes of this nature respectfully and seriously regardless of the circumstances.”
