A MOTORCYCLIST who led police on a high-speed chase after being detected travelling at 50km/h over the speed limit was arrested when police found him hiding behind a wall.

Officers spotted the motorbike on the Pacific Highway at Berowra at 5.30pm on Christmas Day. The rider, 29, ignored directions to stop and continued at speeds of up to 145 km/h in a 90 km/h zone. He was charged with offences including driving recklessly and is due to appear in court in February.

A 27-year-old man was killed after being thrown from his car which careered off the road and hit a boulder.

The crash happened on Christmas Day at Ingleburn, in south-west Sydney, at 7.30pm.

And an elderly man was left a quadriplegic after a four-car crash in Wahroonga. Police believe the accident was caused by a vehicle towing a trailer braking suddenly. Those travelling in the other cars escaped injury but the 77-year-old sustained neck fractures and his 66-year-old female passenger suffered minor fractures. Yesterday three teenagers were hurt after a car overturned on the Hume Highway at Lansvale.

The national road toll stood at 30 last night. Victoria had the worst toll, with 11 people killed, followed by eight in Queensland and six in NSW.
