The family of a 66-year-old man who died six days after he was punched outside a village pub have paid tribute to a "devoted family man".
Leicestershire Police launched a murder investigation after David Darke died in hospital on Saturday.
He had been injured near the Crown Inn in Appleby Magna, North West Leicestershire, on 21 December.
Police said a 36-year-old man initially arrested on suspicion of causing grievous bodily harm had been re-arrested on suspicion of murder.
Officers were called to the pub at about 9.45pm last Sunday.
The force said the victim was outside when he was punched and sustained a serious head injury.

In a statement Mr Darke's family said: "Dave was a deeply loved father to three daughters and a proud grandfather to three boys.
"He was a much-loved brother and a dear friend. Dave will live on forever in our hearts, minds and souls.
"He was a strong, active, intelligent and kind person who was a friend to all. He was a devoted family man with a deep passion for life, the outdoors, nature and walking.
"His life was tragically cut short and he's now reunited with his loving, caring parents. He will be sorely missed by all who knew and loved him."
Detective Inspector Kevin Hames, of the East Midlands Special Operation Murder Investigation Team, said: "The initial investigation resulted in us identifying several witnesses and examining CCTV from the area.
"Those inquiries will continue and the suspect will be re-interviewed by detectives.
"It is an extremely difficult time for Mr Darke's family and specialist officers are supporting them."
