Former British champion boxer turned security guard Julius Francis was caught on camera knocking out a troublemaking punter with a single punch.
The 57-year-old, who competed against Mike Tyson in 2000, now works as a bouncer at BOXPARK venue in Wembley, London.
But despite being retired from the sport since 2007, Francis still packs a serious punch after he was recorded taking out a customer who was abusive towards staff, the Daily Star reports.
In the clip, the man wearing a blue du-rag can be heard screaming “f**k you!” and “I’ll f**k you up!” as he pushes several people in front of him.
Security guards try to nudge him away from a set of guardrails and appeared to be walking away.
But suddenly the rabble-rouser turns to raise his fists at Francis, he is met with a vicious right hook that knocked him clean out.
The viral video was shared on Twitter on June 13, by talkSPORT's boxing editor, Michael Benson, who wrote: "Former British heavyweight champion Julius Francis (who fought Mike Tyson) now working as security at BOXPARK Wembley and dealing with some trouble today…"
Sports Illustrated and DAZN boxing reporter Chris Mannix also added: "When your mouth writes a check…"
Other boxing fans went wild over the clip, as one user tweeted: "Everyone is a “tough guy” until they are not."
Another wrote: "Self defence he was about to attack him."
A third wrote: "That was f**king beautiful. I woke up really p****d off this morning but that’s cheered me up no end. Looking forward to the day ahead now!"
A fourth wrote: "Beautiful.... Quietly moving down the rails all the while yer man was bouncing.... BOSH."
A Boxpark spokesperson said: "Our team are aware of footage being shared online. This incident is currently under review and part of an ongoing investigation, and therefore we are unable to comment further on the incident at this time.
"We would like to stress that the safety and welfare of our customers and our staff is our number one priority."
