A 23-year-old woman was rushed to hospital early yesterday morning after suffering head and facial injuries in a serious single-vehicle crash involving a motorcycle in Warwick.

Police said a passer-by contacted police shortly after 3.30am and reported finding the woman lying on Cobbs Hill Road, near the junction with Middle Road, Warwick, unresponsive but breathing.

The police spokesman said it appeared the victim was riding in a northerly direction along Cobbs Hill Road when she crashed into a wall.

She was attended to at the scene by police and EMT personnel. She was subsequently transported to King Edward VII Memorial Hospital. At 5pm yesterday she remained unresponsive in the intensive care unit.

Cobbs Hill Road was closed between Middle Road and Harbour Road while the scene was processed by traffic collision investigators and officers from the Forensics Unit.

Motorists were advised to use alternative routes to get to their destinations while the exercise continued.
