He also won Spanish- born Camacho’s Commonwealth belt, a belt he relinquished last year to fight Matty Askin for the British Boxing Board of Control (BBBofC) title.
Okolie settled a physical encounter after adapting to Camacho’s southpaw style to secure a fourth-round TKO victory and extend his professional record to 12 straight wins.
Okolie landed a flurry of shots, including a hard clean right hand, and Camacho took a knee with just over a minute left in the fourth. He got up and referee Mark Lyson allowed it to continue, but as soon as Okolie landed another clean right hand, Lyson stepped in to stop the fight.
“I am doing well, 12-0, nine by stoppage. For 12 fights, I think I have done very well.
“For me, staying at British level is pointless, I need to keep pushing and find my level.
“If there is a world title, I believe in myself.”
