Police in Devon and Cornwall are pleased by the public?s response to the knife amnesty, which was launched one week ago. More than 850 knives have been handed in to police stations across the two counties. The vast majority of these are domestic knives but items of interest include a knuckle duster with a blade attachment, handed in at Crownhill in Plymouth, two Kukri military knives in Torquay, a samurai sword at Tiverton and a cane incorporating a sword at Bodmin. Despite the amnesty being knife specific, an anti-tank weapon (rocket launcher) was also handed in at Wadebridge. Spokesman Sgt Dave Anning said: ?We are pleased by the positive reaction from members of the public to the amnesty. ?People seem to be reacting well, handing in a vast array of knives across the force area. We expected around 500 knives and so the actual figure of 860 has exceeded those expectations.? The amnesty is part of a Home Office-led initiative, which runs until June 30. Secured knife bins are positioned at most police stations in Devon and Cornwall to enable those with unwanted weapons to drop them in without fear of prosecution.
