WARNING - distressing content

The family of a little girl whose leg was badly broken in a hit and run outside her Como home have urged the driver responsible to do the right thing and hand themselves in.

Police are searching for the white sedan witnesses say drove away after hitting the girl on her scooter along Greenock Avenue about 6.15pm on Tuesday, March 10.

Mila Davey, 5, was taken by ambulance to Perth Children’s Hospital and is now recovering at home with her right leg set in a cast.

Investigators today released confronting CCTV footage of the incident that show the Mila rolling out of the driveway and being struck by the car in the hope the public can help identify the vehicle.

Her father John Davey said after viewing footage he believed it was incredibly lucky his daughter was not killed.

“I think it could have been a lot worse,” he said. “Every time I see that I think how someone could know they did that and keep driving.

“It hasn’t sunk in to the full extent yet but I just won’t the person who has done it to own up so we can get on with it.”

“It’s been an ordeal. Her sister was right next to her as well and she has taken it pretty bad. We just want it resolved a fast as possible.”

Mr Davey said he accepted the incident might have started as an accident but was turned into something much worse when the driver did not stop.

“She rode on to the road on her scooter at the end of the day but just to drive off and leave her and her sister there - you don’t leave a dog on the side of a road when you hit it - and this is a beautiful five-year-old girl,” he said.

They didn’t even know how bad it was, that’s what gets me.

“They didn’t even know how bad it was, that’s what gets me. Please come forward, I need closure for my little girl and to put this whole thing to bed.”

Witnesses say Mila let out “blood-curdling” screams and was left with a tyre mark across her leg after the incident. She had been playing with her sister and other children in the driveway and was being supervised by adults at the time.

Police are appealing for anyone who can help identify the vehicle involved to contact them.
