Knife arches are being used in Sheffield city centre in a bid to stop weapons getting into pubs and clubs.
They are to be used in the city centre all summer in the hope of reducing violent crime when people are on nights out.
Acting Inspector Louise Lambert is responsible for running the operation in the city centre this summer, said: “Violent crime is an area of real concern for our local communities and for us as a police force, which is why we wanted to re-launch this operation.
“Violence no place on the streets of Sheffield, especially when you’re out and about enjoying the city’s diverse range of nightlife.
“We will have officers outside key licensed venues on busy nights, searching people waiting to go in.
"I appreciate that for some people this may seem like a bit of an inconvenience but I’m sure you’d rather we took that extra step to keep you safe.
“This is in addition to working closely with partner agencies to carry out some early intervention work, reinforced by visits to local schools to talk to young people about the risks of carrying knives or engaging in violent crime.
“We’re also taking the activity a step further and will be routinely carrying out licensing checks and test purchase operations across the city centre venues to make sure everyone is operating lawfully and safely.”
