A 14-year-old boy died after entering the water at Millwall Outer Dock in east London during Monday evening's heatwave, prompting renewed warnings from water safety experts about the hidden dangers of swimming in open water.
According to reports, emergency services recovered the teenager's body after a multi-agency search, with police treating the death as unexpected but not suspicious. As the UK experiences warmer temperatures, experts say drownings often rise because hot weather encourages people to enter deceptively cold rivers, docks and lakes.
