In all, four men and a woman have been jailed for conspiring to traffic women into the UK for sexual exploitation.
The gang trafficked more than 100 women into the UK, some of whom were forced into prostitution and raped, the BBC reported.
Vishal Chaudhary described as "the boss" was sentenced to 12 years while his brother Kunal Chaudhary, 32, got five years in prison.
Vishal and Kunal Chaudhary, along with the three other accomplices, were arrested in early 2013, the report said.
During sentencing Judge Gower said of the gang: "Over a period of six years it exploited hundreds of women and was a sophisticated business. Over the years (it) must have generated hundreds of thousands of pounds."
The court heard that Vishal, of Peninsula Square, Canary Wharf, was the "leading figure in these conspiracies, the boss" and funded a luxury lifestyle from the crime.
Instead they worked in one of the 40 brothels operated by the gang across the city from a base in Brent Cross.
The gang managed their victims from a makeshift call centre in a semi-detached house on a suburban street in Hendon, north London.
