The victim, a 44 year old woman, was walking in New Drove, near the junction with Weasenham Lane when a red car, believed to be a Ford Escort, pulled up alongside her.
A woman got out of the car and punched the victim, knocking her to the floor.

A man was in the same car as the attacker.
He is described as between 35 and 40 years old, with short hair and glasses.
