Fans of the series branded the 54-year-old’s behaviour “disgraceful”.
After the contestants each took home £20,000, Labbett said “well played guys” before promptly leaving the set.
When Labbett’s punch made a loud bang, Bradley Walsh said “Ouch, it just shows you how they take it. They take it very badly.”
He then joked that players should sign up to try and take on Labbett and “rebuild the set he’s just broken”.
It’s unclear whether Labbett was genuinely angry or whether he was playing up to the cameras for effect.
Fans expressed their shock at Labbett’s confrontational behaviour on Twitter.
“Wow! It’s the first time that I’ve seen that type of reaction from the chaser,” one person wrote.
Another said: “I knew there was a reason why he was my least favourite chaser.”
One fan even sent a tweet to Ofcom, writing: “Disgraceful behaviour by Mark Labbett on this evening’s The Chase.”
