The week-long initiative will include an amnesty where knives can be handed in without fear of prosecution, as well as officers conducting extra patrols and speaking to young people about the dangers of carrying weapons.In addition to this, teenagers will be conducting test purchases at retail outlets. This is where someone under the age of 18 attempts to buy a knife to see if they are asked for identification. Possession of weapon offences increased in Cambridgeshire from 487 in 2017 to 527 in 2018 a rise of 8.2 per cent. From today, amnesty bins will be located at Thorpe Wood Police Station in Peterborough, Parkside Police Station in Cambridge and Wisbech Police Station for a week. The maximum penalty for an adult carrying a knife is four years in prison and a fine of £5,000. Inspector Matt Snow said: The action our officers take next week will involve both education and enforcement. Its important that we are talking to young people about the dangers of carrying knives and the potentially devastating consequences. We need local people to have what may be difficult, but incredibly important, conversations. If you know someone who carries a knife please encourage them to make use of the amnesty. You could save a life and prevent the person you know from ruining theirs with a lengthy prison sentence. If people dont make use of the amnesty and they are found to be carrying a knife in a public place they could face a hefty fine and further prosecution by the courts. Anyone who knows someone who carries a knife can also report it anonymously by calling Crimestoppers on 0800 555 111 or visiting https://crimestoppers-uk.org.
