“The victim sustained swelling and bruising to her face, later receiving treatment at hospital.
“We are now appealing for witnesses, dash cam footage and information that may be able to help us progress our enquiries.
“If you believe you can help please call 101 quoting incident number 315 of January 1, 2022.”
