The Hungarian-based gang trafficked at least 120 women into London where they were raped, beaten and forced to work in brothels across the capital.
The six gang members — led by Indian-born Vishal Chaudhary — are among 25 criminals convicted or jailed in the past month alone in a series of operations against Eastern European human trafficking gangs targeting London.
Police say there are an increasing number of joint inquiries with countries such as Poland, Hungary and Romania into prostitution and trafficking gangs.
Scotland Yard said there are at least seven live inquiries into crime groups bringing women into London.
In one operation with Romanian police, the first of its kind, 12 Romanian nationals were jailed for 89 years in their own country for bringing women to Britain to work in prostitution.
In another case earlier this week a Russian madam who ran a “high class” escort agency was jailed for eight years at Southwark crown court. Tatiana Shmyrova, 45, exploited a talented former Bulgarian athlete after she was lured to Britain with the promise of a new life working as a tour guide in London.
The Chaudhary gang trafficked more than 120 women from Hungary into the UK.
