Metropolitan Police data obtained by Exposed News under Freedom of Information legislation reveals that knife crime offences recorded in London reached 14,200 in the twelve months to August 2026 — a 22% increase on the same period a year earlier and the highest annual total since comparable records began in 2014.
The figures arrive against a backdrop of falling stop-and-search activity. The Met conducted 287,000 stop-and-search encounters in the same period, down 18% from 350,000 the previous year. The decline follows revised community-impact guidance issued by the Home Office in January 2026, which required forces to demonstrate “proportionate and evidenced grounds” for each encounter before proceeding.
Victims Getting Younger
Internal Met data, shared with the Mayor’s Violence Reduction Unit and seen by Exposed News, shows the average age of knife crime victims in London fell to 21.3 years in 2025/26, down from 23.1 in 2022/23. Among male victims aged 15 to 19, the rate of hospitalisation following a knife attack rose by 31% year-on-year.
Deputy Commissioner Lynne Owens told the London Assembly’s Police and Crime Committee in September 2026 that the force was “concerned by the trajectory” but cautioned against a “simple correlation” between reduced stop-and-search and rising knife crime. The Met’s own analysis, she said, showed that stop-and-search “alone is not a sufficient deterrent.”
Resources Under Strain
FOI responses from the Met show that the Violent Crime Task Force — the specialist unit responsible for intelligence-led responses to serious youth violence — had 14% of its investigator posts vacant as of July 2026. The force cited “competitive recruitment conditions” and a national shortage of detectives as contributing factors.
The Mayor of London’s office confirmed in August 2026 that an additional £12 million had been allocated to violence reduction programmes for 2026/27, including targeted youth outreach and school-based intervention. Critics, however, have questioned whether preventative spending can offset the operational capacity lost to under-recruitment.
Political Pressure Mounts
Home Secretary James Cleverly faced questions in the Commons in early October 2026 over whether the Home Office guidance on stop-and-search had contributed to the rise. He denied any causal link, pointing to “complex social and economic factors” including post-pandemic disruption to youth services. The opposition called for an independent review of the guidance’s operational impact.
Exposed News has submitted further FOI requests to the 10 largest English police forces outside London to establish whether the knife crime trend is replicated nationally. Responses are expected by November 2026.
