Officers investigating the death of 33 year old Christie McHugh in Barnet are making renewed appeals a week on from her death.
Officers will be in East Barnet Road from 18.00hrs handing out leaflets to the public.
At approx. 18.40hrs on Monday 4 March police were called to East Barnet Road, Barnet, after a woman suffered head injuries.
The ambulance service attended but she was confirmed dead at the scene.
A post-mortem at Finchley Mortuary on Wednesday, 6 March gave cause of death as head injuries.
At this stage it appears she was a driver involved in a dispute with another woman driver.
She left her vehicle and an incident occurred during which she was injured. Early inquiries indicate that she was carried on the bonnet of the other car and fell from the bonnet and was in collision with a Belisha beacon.
The vehicle drove away.
Police subsequently attended an address in Barnet and arrested a woman aged 50 in connection with the inquiry. She was taken to a north west London police station and was subsequently bailed to return in late April pending further enquiries.
A Vauxhall Insignia has been recovered.
