South Yorkshire police have recovered a concealed blade in the form of a credit card in Rotherham.
Officers from a local policing team in Rotherham recovered the blade just off Greasborough Road last night.
They also deployed a knife arch detector overnight in Rotherham town centre to reassure members of the public and help them enjoy a safe night out.
Officers checked over 250 people, but made no arrests.
Anyone with concerns about knives should contact South Yorkshire police on 101.
