A Wodonga boy remains in an induced coma in hospital after being hit by a garbage truck on Monday afternoon.
Those nearby rushed to help Zayne Watts, 6, following the incident on Carkeek Street about 2.15pm on Monday.
Police believe the Cleanaway driver did not realise he had struck the boy and continued driving, but has been co-operative with officers.
Reba Alexander, 13, was one of the people who came to the Wodonga Primary School student's aid.
"I heard two workmen yelling out 'help'," she said.
"I ran out the front door.
"I really didn't know how to take it - it was pretty scary.
"There was blood everywhere."
Those at the scene used towels to apply pressure to his wounds to stem the bleeding.
"He kept nodding off, he was choking on blood," Reba said.
"We had to keep waking him up so he didn't fall asleep.
"He's in Melbourne now, hopefully everything goes okay."
A family friend said the six-year-old had undergone an operation on Monday and was in an induced coma.
The friend said Zayne had injuries including cuts, a large graze on his back where skin was ripped off, and a punctured lung.
"You don't wish this on anyone," he said.
"It's just one of those freaky accidents.
He said Zayne had been riding a bike at the time and was hit in the middle of the road.
