To the untrained eye, it looks like an ordinary walking stick.
But when detectives found this Victorian cane in the back of a taxi, they discovered what may be the key to solving a notorious murder.
For hidden inside the walking stick was a single-barrelled .410-calibre cane gun, capable of killing someone with a single click.
The discovery helped unlock what detectives described as a ‘spider’s web of gun crime’ in London.
Now it can be revealed that the gun broker who supplied this extraordinary weapon to warring drug gangs in the capital also sold a shotgun used in an unsolved murder and multiple shootings.
