Six people in hospital after police pursuit and crash in Gosford on NSW Central Coast

Six people are in hospital, two of them in critical conditions, following a police pursuit and crash on the NSW Central Coast.

Police have launched a critical incident investigation following the two-car collision on Showground Road at Gosford at about 10.30pm.

Officers attempting to stop a car activated lights and sirens but the driver allegedly failed to stop, so a pursuit began.

Police say that after a short distance the pursued car collided with another car.

The driver and front passenger in the pursued car were trapped for a short time before being taken to hospital in critical conditions.

The three rear passengers were also trapped before being released and taken to hospital in serious conditions.

The driver of the other car was also taken to hospital in a serious condition.

A NSW Police critical incident team will investigate the pursuit and crash, assisted by the Crash Investigation Unit.
