The collision involved a black Audi A5 and a Vauxhall Corsa and happened at around 6.40pm on Thursday 14 October 2021 in London Road.
It is reported the Audi had been driving on the wrong side of the road when the incident happened, at a location close to the junction for Lesley Close. A man and a woman are said to have exited the car and fled the scene on foot. A woman driving the Corsa was attended to by ambulance crews and required hospital treatment.
Officers are working to identity the man and woman who were in the Audi. They are also keen to speak to the occupants of a white van that was seen travelling close behind the Audi in the moments leading up to the collision.
