Dwayne was 21 when he marched onto a council estate in east London to retrieve his stolen moped – one that had been lovingly built from scratch by him and his younger brother.
Out of stupidity or anger - he said he couldn't remember which - Dwayne approached the thieves and grabbed his motorcycle. That's when one of them drew a pistol and fired.
"He was about three or four metres away when he pulled the trigger," said Dwayne. "I was fortunate enough that the gun misfired twice."
It was a turning point for Dwayne, who had also survived a stabbing a couple of years earlier, as he feared his younger brother's life might be at risk too.
"Scouting saved me," he said. "I would not have had the confidence to say no to all those voices that were telling me: 'You should go and get that guy who pulled the gun on you.'"
