Police arrested an 18-year-old man when they found him carrying this sheath knife in King's Lynn.

More details of the alleged offence have yet to emerge. But one officer involved in the arrest said there was a chase, tweeting: 'No wonder he ran from police. #hopethesentencereflectsthecrime.'

Police say the number of crimes involving knives in Norfolk remains low.

But carrying a knife life this paracord knife with 4ins blade - which retails for less than £5 - is likely to result in 'a significant sentence' on conviction, according to the Crown Prosecution Service. The maximum penalty for an adult carrying a knife is four years in prison and a fine of £5,000.
