The pair kicked and punched Asaf Ahmed to death
Two teenagers who kicked and punched a man to death outside a social club in Bolton have been given life sentences.
Andrew Smith, 16, and his friend Jason Bolton, 18, both from Deane, attacked Asaf Mahmood Ahmed on 21 December last year, Manchester Crown Court heard.
Smith filmed himself on his phone after the murder as the words "eyes of a killer" were uttered in the background.
Mr Justice MacDuff at Manchester Crown Court said the attack was "callous, unprovoked and lacking in humanity".
He sentenced Smith to a minimum 13 years' detention and gave Bolton a minimum 17-year jail term.
The judge told the court Bolton had been drinking on the night of the attack and set on 28-year-old Mr Ahmed for "fun".
The pair attacked Mr Ahmed as he was walking to a shop. His body was found near the fire exit of the Derby Ward Labour Club on Deane Road.
He had suffered severe head injuries and was clutching an asthma inhaler.
The judge said Smith left the scene after the attack, but Bolton returned and continued to attack him, and kicked Mr Ahmed's inhaler out of his hand.
Tests showed he had died from an acute asthma attack as a result of the trauma brought on in the assault.
Mr Ahmed was found dead behind the club
Mr Justice MacDuff said: "You beat him until he could not move, punching, kicking, stamping until he became motionless and then you returned, Bolton, and when you saw he could get to his hands and knees, you kicked him again until he could move no more."
Police found the seven-second "killer" video clip on Smith's phone, recorded an hour after the attack.
The deputy senior investigating officer in the case, Dave Hickey, said he was shocked when he discovered the footage.
"It's difficult to understand why someone would do that and aggrandise what has happened instead of showing remorse at the death," he said.
"When he found out he had killed someone he bragged about it on his mobile phone."
The judge disputed the boys' claim that they found Mr Ahmed sitting on the steps at the back of the club and said he thought they might have been chasing him.
"There was no reason for him to go round the back of the building into the dark, except to escape from you," he said.
Mr Ahmed had three children. In a statement his family said that he was "a quiet, private man who would not harm anyone".
"We are not a family without him: something is missing," they said.
"We will miss him every day of our lives."
