A teenage girl has been hailed a hero after she threw herself in front of a truck to save her young nephew’s life.

Jayla Wallace, 13, was with her four-year-old nephew Jordyn Prior when the pair got off the bus at 4pm yesterday on Talbot Road near Dongara Circle in Swan View.

But after disembarking the bus, the toddler ran in to the road - in front of oncoming traffic.

Remarkably the teenager’s first instinct was to throw herself in front of Jordyn as an Isuzu Truck came hurtling towards them.

The two were thrown metres into the air resulting in both of them being taken to hospital.

Speaking today Jordyn’s mum said she feared her son was dead.

“She had thrown herself in front of a truck that had overtaken the bus.” Jessy Scattini told 7 News Perth.

“She tried to throw him out of the way.. and they both got hit and were airborne... about five metres.

“I was very conflicted because I love them both so much, who to go to?

“But I could see Jayla was responsive and I could see her bleeding but Jordyn was unresponsive... so I ran to him.”

Jordyn suffered a fractured skull and remains in a stable condition in Perth Children’s Hospital.

Miraculously, Jayla walked away with just grazes and bruises.

But Mrs Scattini says she feels sorry for the driver behind the wheel of the truck.

“We've been wanting to reach out to him to let him know the kids are OK and that I really, really hope he's not having any guilt.”
