A teenager convicted of murdering a man with a "Rambo-style" knife in a street fight in Wolverhampton has been jailed.
Shamari Hanchard-Kerr, 18, was being chased by three men over a debt when he turned and attacked them using disproportionate force, a court heard.
One of the men, Razi Ul-Hassan, died after the attack on 12 August 2010.
Hanchard-Kerr has been sentenced to life and must serve at least 15 years. At the time of the attack he was on bail for attacking two police officers.
Sentencing Hanchard-Kerr at Birmingham Crown Court the judge, Mr Justice Simon, told him he was a bully.
The teenager, of Cheltenham Close, Wolverhampton, was also found guilty of two counts of wounding in relation to the fatal street fight in Crosby Close, Whitmore Reans.
Mr Justice Simon also ordered Hanchard-Kerr to serve 12 years in jail to run concurrently with his life sentence.
The judge accepted he was being pursued by Mr Ul-Hassan, Mr Ul-Hassan's brother and their cousin.
"You then turned and began a violent, unjustified attack.
"What is clear is that you used grossly disproportionate force," Mr Justice Simon said.
The pursuers were stabbed three times each. Two of them survived but Mr Ul-Hassan died from a chest wound.
Hanchard-Kerr's identical twin, Kamahl, of Cheltenham Close, Wolverhampton, was also accused of murder, which he denied.
The jury failed to reach a verdict over the charge.
Kamahl Hanchard-Kerr had previously pleaded guilty to affray and was sentenced to 18 months in prison.
