Police forces across the country will take part in Operation Sceptre, allowing members of the public to hand in knives without prosecution. The last amnesty was held in the first week of May and resulted in 105 knives being recovered. From Monday (July 17) amnesty bins will be located at Thorpe Wood Police Station and Bayard Place in Peterborough, Parkside Police Station in Cambridge, as well as police stations in Cambourne, Ely, March, Huntingdon and Wisbech. From July 2016 to June 2017 there were 220 possession of weapons offences in Cambridgeshire. It is illegal to: Sell a knife of any kind to anyone under 18 years old. Carry a knife in public without good reason - unless its a knife with a folding blade 3 inches long (7.62 cm) or less, eg a Swiss Army knife Carry, buy or sell any type of banned knife Use any knife in a threatening way (even a legal knife, such as a Swiss Army knife) The maximum penalty for an adult carrying a knife is four years in prison and a fine of £5,000. Inspector Ben Newton said: Were continuing to join colleagues across the country in a determination to tackle knife crime. Knife amnesties form an important part of the strategy for Operation Sceptre and Im pleased that more than 100 knives were recovered in May. I hope people will take this additional opportunity to dispose of weapons without fear of prosecution. As part of the campaign were appealing to people, including parents and carers, who know someone who carries a knife to encourage them to make use of the amnesty. 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/.
