Police in Leicester are to increase the number of metal detector arches in the city centre during the World Cup in an effort to deter knife crime.
Although some arches are routinely used, more will be put in place as warmer weather is expected to bring crowds to the city on an evening.
Leicestershire Police said there was currently not a particular problem with knife crime in the city.
Plain clothes officers will watch for anyone trying to avoid the arches.
Supt Stuart Prior said: "The use of metal detector arches are just one part of a much wider programme of preventative, educational and support work aimed at young people across the city.
"Larger numbers of people will be coming into the city centre, especially during the World Cup, and we will be using metal detector arches to increase safety and reassure members of the public.
"Leicester does not have a particular problem with knives and we are determined to make sure that it stays that way. Our aim is to make Leicester a city that everyone can enjoy and feel safe in."
