A man and a woman were seriously injured in what police have described as a "nasty" attack in the early hours of the morning.
A 50-year-old woman was cut a number of times which required stitches while the man, 57, suffered potentially "life-altering head and facial injuries".
Police officers were called just before 2.30am on Sunday, June 23, to a report that two people had been injured in an attack on Carlton Hill.
It happened at the junctions with Albert Avenue and Curzon Avenue, near The Free Man Wetherspoons pub.
East Midlands Ambulance Service crews also attended and treated the victims at the scene of the violent attack.
Detective sergeant Charlotte Henson from Nottinghamshire Police, who is leading the investigation, said: "We have launched an investigation following what is a particularly nasty assault that left both victims requiring medical treatment for their injuries.
“We are particularly keen to trace the suspect in this incident, who was believed to have been with a woman of a similar age in the moments before the assault.
“The man we would like to speak to is described as white, aged in his early-to-mid twenties, is around six feet tall and was wearing a white top. He is believed to have left the scene on foot with the woman in the direction of Carlton Square.
“We are appealing to anyone who was in the Carlton Hill area around the time of this assault to come forward with any information they have or any dashcam footage that they believe could help our teams to identify the man responsible for this assault.”
Anyone who witnessed the incident or who has any information is asked to call Nottinghamshire Police on 101, quoting incident number 129 of 23 June 2019.
