Aminur Nadir Khan, 20, Ali Akbar Choudhury, 20 and Mashudur Rahman, 22, will serve a minimum of 23 years for the murder of Ajmol Alom.
– Detective Inspector Julie Willats, Metropolitan Police
Ajmol was an innocent teenager enjoying a summer evening with his friends when they were targeted in an unprovoked attack by a group of young men with knives. This incident highlights the misery that knife crime causes. I hope the sentence acts as a deterrent to those who carry or use knives or associate with others who do so.
During sentencing Judge Judge Martyn Zeidman said: "This knife madness must end. There has to be a change. But cold figures can never sufficiently reflect the tragic sorrow caused by knife crime. In our case there were two totally unprovoked attacks upon 16-year-old boys."
He added: "The first stabbing was to Rob's face but that did not quench your joint thirst for violence. Within a minute or so you were each a party to the second attack, this time upon Ajmol Alom. You each played a part in bringing his life to an end."
– Family statement
Ajmol was part of us. He had his whole life ahead of him.
We can only hope that other young people turn away from violence and knife crime.
