A woman has been left in hospital with life-threatening injuries after a serious crash on the A595.
Shortly after midnight on Sunday, February 1, police responded to reports of a crash on the A595, near Beckermet.
The crash involved a red BMW 1181 and a woman who was reportedly lying in the road.
The woman, aged in her 40s, was taken to Royal Preston Hospital for treatment.
Her condition is described as critical.
Police said they identified a “potential altercation” near to the scene between a man and the woman involved prior to the crash.
Police added: “This led to the man involved leaving the woman and the area.”
Cumbria Police launched an investigation to establish the movements of the woman prior to the crash.
A 45-year-old man, from Egremont, was then arrested on suspicion of assault causing GBH.
He was interviewed and subsequently bailed pending further enquiries.
