A 42-year-old man has suffered serious, but not life-threatening injuries, after being hit by a motorbike on the Esplanade.
It happened at around 11:30pm last Friday (19th July) when he was crossing the road outside the RBC Building.
Several motorbikes were travelling together at the time, heading towards the tunnel.
The motorcyclist involved in the collision, an 18-year-old man, was also taken to A&E with minor injuries.
The victim was seen by paramedics on the scene and taken to hospital, where he required medical treatment for his injuries.
No arrests have been made.
Police spoke to several witnesses on the night, but still want to hear from anyone who saw what happened.
Anyone with dash-cam footage or video recordings in the area is also asked to come forward.
