Police officers are trying to trace a woman in connection with an assault in Wisbech.
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.
It happened at about 9:20am on Wednesday 5th May.
The victim wasn't badly hurt but did need hospital treatment after the attack.
The attacker is described as white, about 40 years old with shoulder-length dyed blonde hair, medium build.
Police say she was wearing a white sweat-shirt and jeans.
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.
PC Tracey Dodd, from March Police Station, said: "I am appealing to anyone who saw this assault take place or who recognises the description of the attacker to contact me."
Anyone with information is asked to contact PC Dodd at Cambridgeshire Police on 0345 456 456 4 or Crimestoppers, anonymously, on 0800 555 111.
