A man suffered a fractured skull in a late night city attack.
It happened around 3.18am on Sunday (18 August) at the taxi rank on Duncombe Place.
A woman also received a black eye and a number of grazes and bruises.
Following their enquiries, officers released CCTV images of two men and a woman they wanted to speak to, because they believe they have information which would be vital to the investigation.
The people in those images have now been identified.
If you witnessed anything or have any information about the attack, please contact North Yorkshire Police.
