Overview
- The match finished 2–2 on Saturday 19 September 2026 and marked the 100th official meeting between Millwall and West Ham after a 14‑year gap.
- Police carried out a pre-emptive operation prompted by a tip-off that resulted in roughly a dozen detentions of Millwall supporters and stopped an expected off-stadium confrontation.
- The Metropolitan Police ran a heavy security plan that included escorting visiting West Ham fans from South Bermondsey station and increased policing around The Den.
- Social media posts and online challenges helped arrange the planned clash that officers targeted, underlining how digital mobilization now shapes derby risks.
- The rivalry dates to late‑19th‑century dock and shipyard communities and a history of hooliganism, including fatal incidents in 1976 and 1986, which continue to guide policing and fan management today.
