NSW police hurt after wagon rolls

Two police officers have been taken to hospital after they rolled their paddy wagon at an intersection in Sydney's west.

The fully marked caged vehicle had its lights flashing and siren blaring when it went through an intersection at Prairiewood and rolled onto its roof as it negotiated a right-hand turn.

The officers were responding to an urgent job in Carramar just after midnight.

Both officers were taken to Liverpool Hospital, one with an injured shoulder, the other suffering shock.

An investigation into the crash will be conducted by police.
