Detective Chief Inspector Colin Larkin said:
These crimes shocked everybody, not least the five women who were traumatised as a result of being sexually assaulted by this young boy.
For such a young boy to have committed such appalling attacks is both disturbing and unusual.
What is important is that we thank all those members of the public who came forward this weekend after we released an appeal for information. As a direct result, other women who were assaulted by this boy came forward and we were able to present such overwhelming evidence to the courts that the young boy had no choice but to admit his guilt.
More than anything, I am pleased for the women whom this boy sexually assaulted that they have been able to see justice carried out so quickly, and again I would thank members of the public for their support.
