Kangaroo caused motorcycle crash: police

Police believe a crash in Quindalup last night was caused by a man hitting a kangaroo.

At about 6pm on Sunday night, a 50 year old man from Roleystone lost control of his motorcycle on Mewett Road in Quindalup.

The man was thrown from his bike after hitting a sign and a fence on the roadside.

Passers-by assisted the man, who was then flown to Royal Perth Hospital by the RAC Rescue helicopter with serious injuries.
