CCTV has been released of a man who died on Friday evening after suffering a serious assault.
A murder inquiry is underway investigating the death of 48-year-old Emiel Blankert.
Mr Blankert was admitted to King's Mill Hospital on Monday, December 9 suffering severe injuries to his face and chest.
Officers are keen to speak with anyone who may have seen Mr Blankert at around 4pm on Monday 9 December, in the Ladybrook area of Mansfield.
He died on the evening of Friday, December 13.
Detectives think he was the victim of an assault in the days before he was admitted to hospital and are appealing for anyone who knows Emiel or how he came to be injured to get in contact.
Enquiries have established that he entered The Ladybrook pub in Ladybrook Lane at 4.05pm on Monday.
The CCTV images show him in the area sometime after he suffered the attack.
Emiel is white, around 5ft 10ins tall and of medium build. He has green eyes, collar-length brown hair.
Detective Chief Inspector Tony Heydon, who is leading the investigation, said: "We believe that Emiel would have had several injuries at the time this camera picked him up.
"We are continuing to focus on Emiel's movements on Monday afternoon in the vicinity of his home in Ladybrook. Officers are conducting house to house enquiries and viewing CCTV of the area.
"We know that when Emiel went into The Ladybrook pub in Ladybrook Lane that afternoon around 4pm he had already been attacked.
"Please view this image carefully, did you see Emiel that day? I hope it prompts members of the public to come forward. If so, we need to hear from you."
Two women, aged 48 and 27, and a 21-year-old man have been arrested in connection with the incident. They have been bailed pending further enquiries.
A Home Office post-mortem examination has confirmed his injuries were sustained following sustained assault.
Specially trained officers are supporting Emiel's family at this distressing time.
