A woman driver was left fighting for her life after she was allegedly attacked by a male motorist following a car accident in east London.
The 39-year-old woman became unwell after she was assaulted by the other 54-year-old driver in a road rage attack, police believe.
She was given first aid by police officers before paramedics arrived and she was taken to an east London hospital where she remains in a critical condition.
She had been behind the wheel of a Kia Picanto when there was a collision with a Toyota Yaris at the Gants Hill Roundabout in Redbridge just before 7pm on Friday.
