COPS have launched an investigation after a thug was filmed punching Phil Foden’s mum at the Brook vs Khan's boxing fight last night.
The shocking clip, revealed by the Sun, shows the moment a brawl broke out between Claire Foden and a group of men after one calls her Man City ace son a "c***".
And now police said they have launched a probe following the incident.
Greater Manchester Police said: "GMP are aware of a video circulating on social media showing a disturbance at the AO arena last night.
"We are conducting some further enquiries into the circumstances surrounding the incident."
The £100,000-a-week midfielder can be seen stepping in and trying to fend off the yobs - while another man is seen ripping off a fire extinguisher and using it as a weapon.
The clip, which has been widely shared on social media and filmed in a corridor of Manchester's AO Arena, begins with a seething Foden, 21, turning as he appears to be goaded following City's 3-2 defeat to Spurs earlier in the day.
The 21-year-old's girlfriend Rebecca Cooke turns and shouts: "Who you calling a c***?"
The couple then walk into a private room at the arena following Khan's bloody defeat by Kell Brook.
Foden's mum Claire is then seen walking out and asks the group: "Right, who's calling him?"
One of the men replies: "No one."

Claire says: "Right, then f*** off."
She appears to push out at a man in a black jacket, forcing him back several steps, before the attacker steps in and takes a swing at her.
It's not clear if the blow connects, but the 41-year-old reels back and a man in a black baseball hat steps in and punches out in her defence.
Rebecca can be heard screaming: "Claire."
Claire then hits out at two men, repeatedly striking a young blond man in the face. He makes no attempt to strike back.

She also slaps out at the balding assailant who hit her.
A brawl breaks out, with around seven people scrapping in the corridor.
The man in the baseball cap grabs a fire extinguisher from the wall, lunging towards the blond man.
It appears as if he smashes him over the back of the head as he walks away.
The brawler in the hat then lunges out with the appliance twice more before the clip abruptly ends.
England ace Foden, who wears a blue hoodie and jeans, is seen briefly as he tries to defend his mum.
He plays no further role in the fight and doesn't throw a punch.
Rebecca also stands away from the fighting.
ACE'S MUM PUNCHED
Man City bosses have released a statement telling of their "shock" - and say they'll back Foden and his family.
“The club is aware of a video which has circulated on social media showing Phil Foden and his family being harassed and abused," officials said.
"We are shocked and appalled about the nature of the abuse and ensuing assault on one of Phil’s family members.
