Four hurt after police van crash
West Yorkshire Police said none of the three police officers and one civilian driver who were hurt in the incident in Leeds are thought to have life threatening injuries.
A spokeswoman said the collision happened at 11am at the junction of the A61 Regent Street and Skinner Lane, just to the north-east of the city centre: "It is believed the police van had its blue lights and sirens on."
She added: "All of them have been taken to hospital."
The force has appealed for witnesses to come forward.
