Gary Corcoran’s British title battle with Johnny Garton was marred by fighting in the crowd at Brentwood Centre in Essex.
The trouble got so bad that Frank Warren and officials at ringside called for calm and threatened to stop the action.
Corcoran and Garton continued to trade blows as the brawl outside the ropes intensified to further threats of prosecution.
A small minority scrapped on as Garton pulled off a late stoppage victory to take the Lonsdale Belt at 154 pounds.
The fight was a real war and it’s a shame some attempted to spoil the proceedings.
Heavyweight force Nathan Gorman continued his path to a domestic match-up with Daniel Dubois. The Ricky Hatton-trained puncher out-scored Kamil Sokolowski 79-73 on the referee’s card.
With a 14-fight winning streak behind him, Gorman is now ready to be stepped up on his way to a certain British title shot in 2019.
Zak Chelli pulled off the victory of his early career with an entertaining decision over Umar Sadiq.
The pair got involved in decent exchanges, with Chelli managing to down Sadiq on his way to winning 77-74.
Former world-rated Bradley Skeete put his European disappointment behind by recording only the 13th stoppage of his career.
The 31 year-old halted Fernando Valencia for a 28th win from his 30 bouts.
Lucien Reid scored a straightfoward points victory over Rafael Castillo. Reid is now 8-0.
Following Reid, Boy Jones won every round of six against Lesther Cantillano to push his record to 18-1-1.
In the opener, Caoimhin Agyarko won on his debut against Ladislav Nemeth via decision.
Agyarko was the victim of a life-threatening knife attack in 2017 but is now a fully fledged and winning professional.
Also on the card, cruiserweight James Branch Jnr secured a second pro triumph by winning all four sessions against Kent Kauppienan.
