A gang of people smugglers who forced young women into sex slavery have been jailed for a total of more than 50 years.
Police smashed two trafficking networks after victims managed to escape their captors and reported them.
In January an 18-year-old went to officers after suffering two years of forced prostitution.
For much of that time she was kept captive in a flat in The Avenue, West Ealing.
The young Slovakian was moved around the country, forced to have sex with up to six men a day and bought and sold by the pimps.
She was originally recruited in her home country with the promise of bar work by Eduard Facuna working with Roman Pacan, they then sold her to Martin Doci. All three are Albanian.
She was later bought by Ali Arslan, a Turk, for £2,500 before ending up in the hands of Valmir Gjetja, an Albanian who lived with his girlfriend in Avon Road, Greenford.
The 29-year-old made her work in brothels, cut her with a knife, forced her to take cocaine and threatened her with a handgun.
She managed to run away in January and find refuge at a friend's flat but after a few days the thug tracked her down and forced his way in.
He kicked her in the ribs and smashed her head against a wall, knocking her unconscious.
Her friend called the police and the investigations began.
He was sentenced to three years for controlling a prostitute for gain with charges of unlawful wounding and actual bodily harm left on file.
The second network was cracked after a 22-year-old Lithuanian victim escaped from a brothel in Luton. It was raided in December and Ali Arslan and Mesut Arslan were arrested.
