Boy, 6, told 'don't run' before crash

Moments before six-year-old Ryan Leo was fatally struck by a car outside his taekwondo class in Sydney's south, a teenage witness heard someone say "don't run".

The "confident and outgoing" six-year-old was in the care of a paid nanny when he was hit by a car on Durham Street, Hurstville, on July 28 last year.

A teenage boy told an inquest into Ryan's death on Monday that he saw the car that Leo was in park and heard someone tell the six-year-old not to run.
