Nottinghamshire Police have relaunched an appeal for information to help their investigation after a 46-year-old man who was found collapsed in Mansfield has died in hospital.
The man was found on Clumber Street at around 6.35am on Wednesday (March 14) and died later the same day.
Officers are still trying to establish his movements before he was found and believe there may be people who saw him walking around the area who have not yet come forward.
Anyone who drove past the area at the time who has dashcam footage may also be able to help.
If you can help with the investigation, you are asked to contact Notts Police on 101 quoting incident number 66 of March 14.
