Neighbourhood police teams are carrying out targeted patrols after officers seized knives and other weapons in Mangotsfield on Wednesday.
Police were called to St James Place at about 4.20pm by witnesses reporting seeing three teenage boys armed with a large knife.
Specialist firearms units were on the scene within minutes and four boys were arrested for affray.
One, aged 15, was also arrested on suspicion of possessing an offensive weapon in public and possession of cannabis. The other three, aged 15 and 16, were also arrested on suspicion of possessing a knife in public.
One of them, aged 16, was further arrested on suspicion of possessing an electrical incapacitation device.
Officers seized a number of knives and other weapons from a nearby address. All four boys were later released on police bail pending further inquiries.
A police spokesperson said: “The investigation continues. If you witnessed the incident or have any dashcam or smart doorbell footage which could help, please call 101 quoting reference 5221091761.
“Alternatively ring the independent charity Crimestoppers 100 per cent anonymously on 0800 555 111.”
Police say that despite the headlines, carrying a knife is not the norm – but it’s still something they take very seriously.

Anyone concerned that someone they care for carries a knife is urged to talk to them about it and encourage them to surrender it. As well as the permanent knife surrender bins at police buildings in Patchway, Staple Hill, Kingswood, The Bridewell, Keynsham, Weston, Bridgwater & Radstock, there are temporary bins at police sites in Frome, Wells, Trinity Road, Bath and Broadbury Road this week as part of Operation Sceptre.
