Welcome to the briefing room with me, David Daronovich. In this week's episode, I'm delving into the underworld of Pakistani drugs gangs in West Yorkshire.

On the 2nd of January 2017, police shot dead 28-year-old Mohammed Yasser Yakub

on a motorway slip road near Huddersfield.

Their target was apparently armed and dangerous, a big-time drug dealer,

allegedly with a record of using violence to get his way.

That was not how his family saw him.

All I can say, I've known him for a very long time.

I've spent every single day with him,

and I know he's not a person who would shoot at anybody.

He hasn't got a bad past because he's not being convicted of anything.

Yasser Yacoub's death was followed by protests on the streets of Bradford

and in nearby Huddersfield, hundreds turned up to a mosque for his funeral.

As I watched on TV the crowds of grieving men and women dressed in Muslim garb,

I marveled at how such a religiously conservative

community could contain within it such a dangerous criminal element, because the fact appears to be

that the drugs business in West Yorkshire is largely controlled by gangs of Pakistani Muslim

heritage who use their community contacts

to aid their criminal operations.

How has this developed and how is it carried out?

I headed to Dewsbury to try and find out.

Duesbury in the 19th century was a very wealthy town.

Three railway stations.
