WA dad sped while child slept unrestrained

A man has been caught driving at 168kmph on a West Australian highway while his four-year-old daughter slept in the back seat without a seatbelt.

Police stopped a Ford Falcon speeding in a 110kmph zone on Great Southern Highway in Woottating, east of Perth, on Saturday afternoon.

They say they found the driver's young daughter asleep and unrestrained in the back of the car.

The man, 33, was charged with reckless driving and his car seized.

Further charges are expected to be laid.
