Police say they have questioned a 50-year-old woman in connection with the death of a woman following a road accident in Barnet, London.
She was taken to a north west London police station and was subsequently bailed to return in late April pending further enquiries.
Police said that early inquiries indicate the deceased woman was carried on the bonnet of another car following a dispute between the two drivers.
