Police and paramedics were called to The Crow's Nest pub in Cwmbran on 1 August
The son of a 102-year-old great-grandfather who died after allegedly being assaulted at a south Wales pub says he was a "pub character".
Phillip Ormerod, from Cwmbran, Torfaen, was taken to hospital in a critical condition following the incident at the Crow's Nest pub in the town on 1 August.
Gwent Police confirmed on Thursday that he had since died.
A 56-year-old man from Llanelli, Carmarthenshire, was arrested on suspicion of inflicting grievous bodily harm, and remains under investigation.
Ormerod's son, Robert Ormerod, said his dad had been diagnosed with dementia and was a widower who lived alone.
Phillip Ormerod was a "pub character" who was diagnosed with dementia, his son says
"I feel sad – even though he could be difficult because of his age and dementia, still, you get used to him being around," he said.
"Even though I suppose he wouldn't go on forever, he would've carried on I think for a bit."
Robert Ormerod, a retired civil engineer, said his father used to visit the Crow's Nest regularly and described him as a popular character who young people would buy beer for when he visited the bar.
"What happened is not nice. The pub has changed a lot over the years. It has become a youngsters' pub," he said.
"Me and my brother would visit our father regularly and clean the house.
"His eyesight had deteriorated and he had been diagnosed with dementia two or three years ago.
"He walked to the pub two or three times a week… he was a beer drinker and I suppose some people saw him as a bit of a character at his age."
Robert Ormerod said his father Phillip was a regular at the Crow's Nest pub and was well-known by fellow punters
