A teenager who murdered a man in a revenge attack has been branded a remorseless killer and locked up for at least 12 years.

A judge yesterday told Guyan Guthrie, 18, he had shown no regret over the death of Rashid Elahi.

“You are not in the least bit concerned about what happened,” Mr Justice Griffith Williams said.

He ordered Guthrie, 17 at the time of the murder, to be detained at Her Majesty’s pleasure. He will not be able to apply for parole for 12 years.

Guthrie, of Canterbury Avenue, Bradford, was convicted by a jury at Bradford Crown Court on Monday of murdering Mr Elahi, 21, of Ryan Street, West Bowling, Bradford, on July 25 last year.

He was also found guilty of wounding Tajambal Salim, of West Bowling, with intent to cause him grievous bodily harm.

Anasta Decosta, 26, also of Canterbury Avenue, was jailed for 15 months for unlawfully wounding Shahid Iqbal.

All three victims were attacked in daylight in Gaythorne Road, West Bowling. The judge said Guthrie and Decosta were armed with knives for a revenge mission after Guthrie was attacked near Newby School.

Mr Justice Griffith Williams rejected Guthrie’s claim that he was badly beaten up, saying he received minimal injuries in a one-to-one fight.

Guthrie, looking for a lone Asian to attack, stabbed Mr Salim in the back, inflicting a life-threatening wound.

Guthrie then went for Mr Elahi, who was posing no threat. He stabbed him downwards with such force that the knife cut through two bones and went into his lung.

“Nothing that happened in Gaythorne Road this Friday last July can justify such disproportionate behaviour on your part,” the judge said.

Guthrie’s barrister, Alan Newman QC, said he had been attacked by groups of Asians twice before, and the attack that day was “the straw that broke the camel’s back”.

Decosta’s barrister, Rag Chand, said he was “a good and decent man”.

After Guthrie was sentenced, Detective Superin-tendent Tim Forber, who led the investigation, said: “This conviction and sentence should send a clear message that those who carry knives and use knives to commit violence will be brought to justice.

“I want to thank all the members of the community who came forward with information.”

Noor Elahi, Rashid's brother, said his family was devastated and shattered by his murder.

Mr Elahi, 38, of West Bowling, said his brother had left a widow aged 20.

“Rashid was kind-hearted and a good guy,” he said. “He was in the wrong place at the wrong time."
