Chapter One - The Call (Catching a Criminal Series Two)

In February 2018, officers from Derbyshire police found themselves 1,000 miles away on the streets of rural Latvia.
Alongside an elite group of Latvian State Police officers, they executed warrants of the dead of night, hunting for the ringleaders of a human trafficking gang.
It was the culmination of a massive operation, stretching from the streets of Derby to the Baltic States, following a financial paper trail that unearthed wealth, fast cars, mansions - and nearly 30 vulnerable people, paying for it all.
It was the largest human trafficking operation ever carried out in Derbyshire, one that proved how slavery and labour exploitation is very much alive today.
In this series, we will show you how an organised criminal gang were finally brought back to the UK to face justice, and how their criminal empire came crashing down - thanks to one single phone call.
That initial call - about a man assaulting a woman on a street in Normanton - led police to a nearby house to try and safeguard the victim and track down the attacker.
But it quickly became apparent that there was more to the call than the officers initially thought.
