Yesterday evening, say police, a woman in her 40s was walking at Spencer Road when a car with three men on board stopped beside her.
Detective Inspector Conor McStravick told Derry Daily: “One of the males got out of the car and assaulted the woman.
“She managed to get away and ran to a safe location. She was not hurt.
“Police are appealing for any information to assist in identifying the vehicle or persons involved.”
The car is believed to be a Volkswagen Passat or a similar type of car.
