Richard Towers (then known as Hayles) was imprisoned for 13 years after being part of a gang which inflicted three days of agony on a man who was held at gunpoint, and tortured with a steam iron, hammer and stun gun.
He played no part in the man's ordeal but was involved in the kidnap which led to a £150,000 ransom demand.
2009 Towers turned professional on 13 June 2009, scoring a points victory against Chris Woollas.
Towers fought in another three bouts in 2009, against Michal Skierniewski, Jason Callum and Lee Mountford, winning all within the scheduled rounds.
2010 Towers managed routine knockout victories over Yavor Marinchev and Ladislav Kovarik.
