A policeman has tweeted a shocking picture of a gigantic knife he seized on the streets of London.

Sgt David Hunt was called to reports that youths were smoking cannabis in the stairwell of a housing block near Elephant and Castle in Southwark.

He posted a picture of his colleague, PC Osborne, holding the terrifying weapon.

Hunt said the find was unusual in his ward, adding on Twitter: "The worrying thing is why did they have it in the first place?"
