The truth is that this case, though extreme, is far from isolated. Modern day slavery is on the rise. Human beings - especially women and children - are being trafficked into and within the UK to work as labourers, domestic servants, prostitutes, cannabis farmers, forced beggars and a range of other jobs.
Debt is a form of slavery and the Biblical message is one of release from slavery, of freeing of captives. It cannot be a mark of a civilised society that it is based on enslavement through debt. Peter Selby reminded us passionately that debt, interest and the slavery of the poor is condemned by God and the prophets in both Christian and Muslim religious traditions.
The human trafficking industry - already the most profitable international criminal enterprise after the drugs and arms trades - is posting higher profits than ever. In 2005, UN estimated that it was a $32billion per year industry, based on International Labor Organization estimates that 20.9 million people suffered from forced slavery.
When you're dealing with victims of crime it can sometimes be what you don't know that's most disturbing. How many more of them are out there? What are the signs that we missed? Are we spotting others before it's too late? Nobody could have failed to be affected by the harrowing story of a 10-year-old girl trafficked from her home in Pakistan to Manchester.
I have to admit to a certain amount of confusion of late. I was asked recently by a friend 'what' I considered myself. I live in Scotland and here, in the run up to the referendum on independence next autumn, most people are trying to figure out, in essence, if they're more Scottish than British or vice versa.
The outrage at such severe abuses mirrors responses to human trafficking and 'modern day slavery', as all agree that exploitation should not have a place in our supply chains. But whether low pay or excessive hours, bonded labour or human trafficking, the common thread is profits trumping rights and talk in place of action.
Back in the city we meet with ex-prostitutes who have been rescued and are trying to transition to a new life. One young girl's father was murdered by trafficking criminals, so unhappy were they over the loss of 'property' and revenue.There's not much mercy to be found in the heart of the slave holder; even in Varanasi, the city of salvation.
Human trafficking is a scourge. It does not discriminate and permeates across age, race, sex and gender; it crushes self confidence and destroys lives. Its victims are often some of the most vulnerable members of society, separated from family and friends and with no access to financial help or support, they can become forgotten victims. As victims' minister my role is to ensure that they are not forgotten, but it is a job I can't do alone.
