Mike Tyson's former opponent knocks out man while working as a security guard

This shocking footage shows the moment former professional boxer Julius Francis knocked out a man with a single punch while working as a security guard outside BOXPARK at Wembley Stadium.

The former British heavyweight champion, 57, was dismissed inside two rounds by Mike Tyson in their Manchester showdown in January 2000 – snapping a three-fight winning streak in the process.

Francis, who is also a grandfather, walked away from boxing with a 23-24-1 record.

He has spent the past few years working as a security guard to support his family.

And now Francis has gone viral after footage emerged on social media of him knocking out a man with a single punch during a street brawl.

A group of men were filmed having a dispute outside BOXPARK in Wembley, London on June 14.

One of them, a man wearing a blue durag, appears to be behaving in an aggressive manner, as footage shows him taking a couple of swings at a group of men standing behind the barriers.

The security guard can be seen backing away from the other man, who continues to act aggressively, as he tries to take stock of what is going on.
