The father of boxer Ricky Hatton was arrested on suspicion of assaulting his son the day before he announced his comeback, it has emerged.
Ray Hatton, 61, was given a police caution following the incident outside Ricky's Greater Manchester gym on Market Street, Hyde, on Thursday.
It is understood that Hatton, 33, had to protect himself during a heated row in the car park but was not injured.
Both Ray Hatton and his son's agent declined to comment on the incident.
A Greater Manchester Police spokesman said: "Shortly before 11:45 BST on Thursday, police received reports that there had been a fight involving two men outside a health and fitness club on Market Street.
"A 33-year-old man was assaulted by a 61-year-old man, who was arrested on suspicion of common assault and subsequently given a police caution."
On Friday, Ricky Hatton announced he would be returning to the ring, more than three years since his last bout.
He said: "It's more than a comeback. I'm fighting to redeem myself."
Hatton was stripped of his licence to box in September 2010 and fined £20,000 plus costs after allegations he used cocaine.
He then spent time in a rehabilitation clinic.
The boxer officially retired in 2011 with a record of 45 wins and two defeats.
