The terror a teenage boy brought to South Liverpool as the leader of a gun toting drug gang can today be exposed in full.
Harry O'Brien was described as a child with ADHD and a "defiance disorder" who had a "disrupted education". But at the age of just 16, the baby-faced cannabis dealer became the boss of a teen crew behind three terrifying shootings and a firebombing.
The ECHO won a legal battle to name O'Brien, when the now 17-year-old was locked up for the brutality he brought to the streets of this city. Now we can reveal how he exploited fellow children and men nearly twice his age to carry out his bidding.
