Overview
- Emergency services launched a large search after reports a boy entered Millwall Outer Dock on Monday evening and recovered his body at about 10:30pm.
- The Metropolitan Police have informed and are supporting next of kin and have urged people to only swim in designated areas while they prepare a report for the coroner.
- The dock is marked as a no‑swimming area with warnings of deep water but has a deck used for jumping, and witnesses said the boy was part of a group using the site to cool off.
- Local residents told reporters that wardens previously paid for by Tower Hamlets Council were removed and have called for patrols or lifeguards to be reinstated to deter risky behaviour.
- Safety groups and emergency services have warned that hot weather has driven more people into unsupervised waterways and that the incident could prompt renewed reviews of local patrols, signage and public safety campaigns.
