London-born Turner boxed his way into a commanding lead, but when the grueling nature of a 12-round fight started to take effect, Rafferty, who now boasts a perfect record of 24 wins (with 15 ko's) in the paid ranks, took control.
In that ninth round, Raffery blasted a visibly exhausted Turner, who could not escape from the ropes.
A violent volley of blows to head and body sent Turner reeling, before Rafferty - aka the Demolition Man - plunged a punch into his rival’s stomach.
Turner went down to the canvas, shocked and hurt, and all but beaten.
He was then pulled out of the contest by his corner.
After the fight, a clearly emotional Rafferty said: "I’ve worked 18 years for this, dreamed of it.
"I thought it was man versus boy tonight, but it was man versus man.
"When he gets older, he’ll be some fighter."
So what's next for the new British champion?
"I’m going to go and see my girlfriend," Rafferty said.
"I’ve not seen her since March.
“I’ve not even gone to see my mum’s grave, I’ll be dressing her up in the gold stuff.”
