Police in York are appealing to the men shown in these CCTV images to come forward.
Officers believe they were in the King’s Staith area if the city centre in the minutes leading up to an incident during the early hours of Saturday 20 April, when 29-year-old Steven O’Neill sadly died after he entered the River Ouse.
The men are believed to have been on a night out in the city on Friday, 19 April 2019 and the early hours of the next day.
Officers believe they could have important information that could assist their investigation into the events that led up to Steven’s death.
In addition to the local investigation, an investigation by the Independent Office for Police conduct remains ongoing after the case was referred to them by North Yorkshire Police due to police contact with Steven prior to his death.
North Yorkshire Police are urging any of the men who recognise themselves from the images, or anyone who thinks they may know the men, to call 101, select option 2 and ask for York CID.
