A ‘weapons sweep’ in the Stonebridge ward has uncovered four blades and a used syringe.
Officers found the potentially deadly arsenal during a search of green space including bushes and tress where criminals hide their weapons.
They uploaded an image of their find on social networking site twitter from their @MPSStonebridge account.
Three days ago a knife with a seven centimetre blade was laso seized in Brent.
The searches are being carried as part of Operation Sceptre which is tackling knife crime.
The week-long intelligence led initiative consists of specialist officers from the Trident and Area Crime Command, along with Safer Neighbourhoods Teams, conducting high visibility patrols in places where people may be carrying or using knives illegally.
In addition to weapon sweeps and stop-and-searches, officers will also be carrying test purchases to weed out dodgy traders who are prepared to sell bladed items to anyone under the legal age of 18.
Detective Chief Superintendent Kevin Southworth, head of Trident and Area Crime Command said: “Far too many families have been devastated by the impact of knives and one young life lost is one life too many.
“We are committed to doing all we can to reduce knife crime, tackle London’s gangs and take more knives and weapons off our streets.”
