Detectives investigating an incident at Cardigan Fields have released CCTV images of a man and a woman they want to speak to.
The incident occurred in early hours of Sunday, July 1, in the car park of McDonalds, off Kirkstall Road.
The male suspect, who was driver of a white Audi A1, and the female, who was the front seat passenger, got into an altercation with a group of people who were parked up next to them in a black and white taxi.
The male suspect allegedly punched a man from the taxi once to the face, knocking him out momentarily. The same man then forcibly removed his car keys from a woman, causing serious injuries to her wrist.
Anyone who recognises the man or the woman shown in the CCTV images or who has any with information that could help the investigation is asked to contact DC 3023 Sam Shukla at Elland Road via 101 quoting crime number 13180320660 or call the independent charity Crimestoppers anonymously on 0800 555 111.
