A seventh man has been arrested over a crash which left a young mum from Halifax dead and her two children and boyfriend injured.
The 25-year-old has been arrested on suspicion of causing death by dangerous driving after the accident in Boothtown which killed Emily Phillips.
A 19-year-old man from Bradford previously arrested on suspicion of causing death by dangerous driving has been released on bail pending further inquiries.
Five other men also arrested on suspicion of causing death by dangerous driving have been released with no further action.
The accident happened at around 3.30pm on Sunday when a Vauxhall Astra, which was travelling from Chester Road, crossing the A647 Boothtown Road to go onto Woodlands Road, was involved in a collision with a black Seat Leon travelling on Boothtown Road towards Halifax.
Emily, 25, was the front seat passenger of the Astra. She was pronounced dead at the scene.
The male driver, aged 26, and two passengers who are Emily and the driver’s children – a girl aged seven and a boy aged four - were taken to hospitals.
The two children remain in hospital with minor injuries.
The 26-year-old man also remains in hospital in a serious but not life-threatening condition.
Anyone who can help with the police’s investigation is being asked to call West Yorkshire Police’s Homicide and Major Enquiries Team on 101.
