Officers are appealing for information after a woman was reportedly assaulted in a bar.
The victim was on the dancefloor at a venue in Goose Gate, Nottingham, when she was approached by a man and grabbed by the throat.
The man is then alleged to have made a homophobic comment.
Enquiries, including reviewing CCTV, have been ongoing since the incident, which happened at around 1.05am on Wednesday 6 April 2022.
Officers have now released images of three people they would like to speak to as the investigation continues.
Sergeant Chris Johnson, of Nottinghamshire Police, said: “The behaviour reported is unacceptable and we are working hard to understand the circumstances of what happened. The woman was simply enjoying a night out and this is not how anyone should expect their evening to end.
“We have now released images of three people we would like to speak to. We believe they may have important information which could help our enquiries.
“We are determined to find those responsible and would ask anyone who recognises these men, or anyone who witnessed the incident or has further information, to get in touch with Nottinghamshire Police on 101, quoting incident 31 of 6 April 2022.”
Anyone with information can also report this anonymously through the independent charity Crimestoppers on 0800 555 111.
