Witnesses say a heroic day-tripper managed to haul two children back to shore during an incident where a mother and daughter drowned. Beverly Smit, 60, described the unnamed rescuer swimming out to sea three times as the tragedy unfolded in West Mersea, near Colchester, on Wednesday evening. Shelina Rahman, 41, and Sameeha Rahman, 15, were trying to rescue a seven-year-old boy from the water when they got into difficulty and died. Recalling the moment the "Good Samaritan" sprang into action, Smit said: "They were calling for help and the children and adults were out there. People have described how bystanders rushed to the water to help, including teenagers who worked at the nearby Seaview Beach Diner and an off-duty paramedic.
