A man from Surrey who drowned after rescuing a four-year-old from the sea has been hailed a hero.
Witnesses say the unnamed man from Sutton in Surrey went into the water over the weekend when he saw the child struggling in a rubber ring - despite red flags warning of dangerous currents.
But the man, who was not related to the youngster, had a heart attack and drowned moments after delivering the child to safety.
