Three men have been arrested after a crash which left a woman fighting for her life.
All three were held on suspicion of dangerous driving after the two-car crash in the centre of Birkby .
A second woman was also badly hurt but two youngsters in the back of one of the cars escaped injury.
Police sealed off the scene for several hours on Thursday evening after the crash as a major investigation was launched.

She remains in a “serious” condition in hospital.

Huddersfield fire watch commander, Andy Rose, attended with one of his crews and one from Rastrick .
“It was a serious collision.
“We had to cut out several people but managed to get the children out without doing this by going through the back.”
Det Con Sam Davies, of West Yorkshire Police’s Major Collision Enquiry Team, said: “I would appeal to anyone who was in the area on Thursday evening and may have seen either vehicle prior to the incident, or witnessed the collision itself to come forward.
“Information can be passed to the Major Collision Enquiry Team by calling 101.”
