A ruthless gang that lured victims from Poland to the UK is believed to have enslaved around 300 vulnerable people.

Members of the gang lured their victims to the West Midlands with false promises of free travel, accommodation and jobs paying £300 a week, but the people were held captive in squalid conditions, some having to wash in canals and eat from skips.

Eight members of the gang who are thought to have made £2m cashing in on the misery of others are now behind bars.
