Following the sentencing of three men over the shooting of Thusha Kamaleswaran, Detective Superintendent Gordon Allison issued the following statement.
The shooting of five-year-old Thusha Kamaleswaran was "an attack on society itself by men who saw themselves above and outside the law" according to the judge.
As he sentenced them to life in prison, he called the case "exceptional and of the utmost gravity".
The three men convicted over the shooting of five-year-old Thusha Kamaleswaran, which left her paralysed and in a wheelchair, have been sentenced to life in prison with minium terms of:
14 years for 20-year-old Anthony McCalla
14 years for 19-year-old Kaseem Kolawole
17 years for 21-year-old Nathaniel Grant.
The judge is now giving his comments before sentencing.
He has told the defendants that their crimes were of the utmost gravity and that when they set off on their bikes it was as if they were "on a mission".
All three defendants stared straight ahead as the judge told them "not one of you has shown a shred of remorse".
Three men convicted over the shooting of five-year-old Thusha Kamaleswaran are in the dock and about to be sentenced.
Thusha's parents have taken their seats in court and relatives of the other victim, Roshan SelaKumar, are also in court.
