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.
