Boy in Royal Children's Hospital after being hit by car in Heyfield

A BOY was been flown to Melbourne's Royal Children's Hospital in a critical condition on Friday following an incident in Heyfield.

Paramedics were called about 3.45pm after the boy, believed to be a student in his first year at secondary school, was struck by a car at the intersection of Mary and Anderson Sts after getting off a bus.

He suffered life-threatening upper body injuries.

The driver of the vehicle, who was uninjured, stopped to help after the collision.

The Age reported a woman, whose children take the same bus, was at a nearby house when she heard a car screech to a halt.

"The first thing I saw was a sneaker on the road and I literally felt sick.

"Then I saw him lying on the ground unconscious but still breathing," said the woman, who wished to remain anonymous.

"There were lots of school kids and his friends who were all very upset ... it was horrendous."

The woman said the boy was a Year 7 student in his first week of high school.
