Ronald Hayes: Family's tribute to Chester pub attack victim
A 63-year-old man who died after he was near a Chester pub had a "drive for life that outweighed his years", his family has said.
Ronald Hayes, from Northumberland, died two days after the attack near the Liverpool Arms in Northgate Street about 00:50 GMT on Saturday.
Two men, both aged 26, were initially arrested on suspicion of assault but could now face a more serious charge.
In a tribute his family said: "We are all deeply saddened."
Ventilator switched off
The statement added: "Those closest to Ronald describe him as a doting partner, father and grandfather whose spirit and energy was infectious.
"He had a drive for life that outweighed his years."
A post-mortem examination was due to take place earlier.
Mr Hayes, of Morpeth, had been in the Liverpool Arms Bar and was attacked after leaving the premises, police said.
Officers believe his attackers were also in the bar during the evening.
Mr Hayes was taken to the Countess of Chester Hospital in a critical condition where doctors placed him on a ventilator.
The ventilator was switched off shortly before 13:00 GMT on Monday.
The two men, from the Ellesmere port area, have been bailed.
