Brooke Kinsella has said the life sentences handed out to her brother's killers were "not really enough".
The former EastEnders actress, 25, was in court to see Juress Kika, 19, Jade Braithwaite, 18, and Michael Alleyne, 20 given life sentences with minimum terms of 19 years for killing Ben, her 16-year-old brother
Following the sentencing, Brooke said: "It's good enough but it is little more than Ben lived, so it is not really enough."
Ben and his friends had been to a bar to celebrate the end of their GCSE exams when a row broke out in Islington, north London, in June last year.
Although the confrontation had nothing to do with him, he was chased along the street with other youngsters - and stabbed to death when he stopped running.
After the trio were found guilty, Brooke - who played Kelly Taylor in EastEnders - said: "I am overjoyed. It's awful, awful, but we got all we needed - it's justice. There is never going to be enough justice but we have got it now."Reuse content
