Horrifying new photographs show the full extent of a country-wide knife amnesty with thousands handed into police forces across Britain.
Images show bins of blades collected during the national event which ran between March 11 and 17.
Many forces saw their biggest ever haul of weapons handed in, with banned butterfly knives, samurai swords and designer blades left in special bins.
The amnesty was part of a national campaign, Operation Sceptre, run by police forces across the country to reduce the number of illegal knives in circulation.
