Watch Suspect No. 1

Humberside Police are facing a rise in crimes involving knives and offensive weapons. This edition follows three investigations, revealing the specialist tactics used by CID to fight this rise in violent crime.

A household is terrorised at home by five masked men who break in and hold them at knifepoint before stealing their car. Can detectives find the violent gang before they strike again?

A man is viciously attacked on his doorstep with what appears to be a gun. Armed police arrest a gang of four for the terrifying assault. But but it's a race against time to prove they have the right men.

In Scunthorpe, a restaurant worker is stabbed in the neck with a pair of scissors in broad daylight before the attacker flees. Can police find and build a case against their suspect?

In Grimsby, a vicious mass street brawl leaves innocent victims with serious injuries. Police are thrown into a desperate race against time to find before a suspect flees the country.
