“The junction where the incident occurred is a busy junction and anyone in the area at the time - who witnessed what happened - is urged to make contact. People are also asked to check dashboard cameras or private CCTV for any footage which may be relevant.
“I would also like to urge people to consider the impact on the family of the victim and refrain from sharing footage online, which we know has been circulating.
