This is where we keep all our seized exhibits.

At a secret location near Heathrow Airport, I'm shown a room full of past seizures.

Danny Hewitt from Border Force says organised crime is behind the trade, but some customers here don't even realise what they're doing

When we see the movement of people and the settlement of communities in the UK, it drives a certain demand for traditional items, medicines, cultural items that may not have been illegal in other parts of the world but are illegal in the UK.

A trade increasingly driven by social media.

Back to the caged tiger on Facebook.

A Chinese seller offers me a tooth for $280.

$280.

A hand sifts through pangolin scales.

Facebook again.

The price, $150 for one kilo.

And a phone call to a man who wants to sell me dead seahorses for use in food or traditional medicine.

How much for a kilo?

There are sellers right here in the UK.

I contact one in the north of England and they're happy to sell me a pack.

I've just picked up my package from a post office box.

It only took two days to get here.

If I look inside, there's three packets full of dead, dried seahorses.

Now, selling them to me like this in the UK, that's against the law.

I'm just going to rip along the top here and see if we can...
