Two men have been jailed for a total of ten years for human trafficking offences and running nine brothels in Derby, Chesterfield and Lincoln.
Derby Crown Court heard the case was one of 'modern day slavery' with vulnerable Chinese and Malaysian women trafficked around the country.
Meyrick Bramhill-Purchase and Mo Quan Zhou were arrested last May and later charged with seven crimes relating to prostitution and modern slavery.
Following a ten-week trial at Derby Crown Court, the pair have now been found guilty of some of the charges and jailed.
Zhou (45), from Derby, was jailed for five-and-a-half years and Bramhill-Purchase (64), from Witham St Hughs, for four-and-a-half years.
Officers unearthed evidence of nine brothels; two in Derby, two in Chesterfield and five in Lincoln. Vulnerable Chinese and Malaysian women were found at the houses, having been trafficked around the country.
Both Bramhill-Purchase and Zhou had rented the properties and paid for adverts on escort websites to attract customers to the brothels.
