Crowd disturbances marred Young Mutley's British and Commonwealth title bout at the Aston Events Centre last night.
The West Bromwich welterweight delivered a performance of seismic proportions to dominate before being stopped after two minutes 18 seconds of the tenth round after a barrage of Kevin Anderson punches.
However, when referee Phil Edwards called a halt, an outbreak of violence among supporters ensued.
A group of Mutley's fans charged towards Anderson's band and there was an unpleasant exchange for five minutes before order was restored.
Mutley's reputation was greatly enhanced while Anderson proved his moral fibre.
Mutley and Anderson adopted a cautious early approach but a guttural roar of 'Mutley' permeated the arena as the Midlander took control and unleashed a peach of a left hook that left Anderson prostrate.
The unbeaten Scot rose quickly and took the mandatory count of eight but was visibly shaking. Mutley advanced with menace but Anderson hung on for the remaining 30 seconds of the round.
Both boxers took a breather in the third round but a head clash in the fourth opened a cut on Anderson's right eyebrow. Mutley unleashed a barrage of punches that shook Anderson and left him sagging on the ropes. Mutley look focused and totally in control while Anderson repeatedly looked to his corner with an air of resignation.
Mutley's sickening body and head shots were disconcerting the Commonwealth champion. Round five and six pursued the same pattern with Anderson advancing but Mutley continually picked him off with punishing left hooks.
Whenever Anderson threatened, he was stopped by Mutley and as the sixth round expired, the underdog was in complete control.
In the next three rounds Commonwealth champion Anderson worked his way back into the bout. However, Mutley, having to negotiate the last three rounds to emerge victorious, was caught with a sucker punch in the tenth.
A huge right hook by Anderson left him sagging, a flurry of unanswered punches left Mutley reeling on the ropes and Edwards called a halt.
