A 16-year-old boy led a mob of teenage thugs in three shootings and a terrifying arson attack.
Harry O'Brien controlled a "graft" line and a crew of dealers selling cannabis on the streets of Dingle. But his "lucrative" trade was exposed after a "feud" led to three shootings in three weeks in South Liverpool.
One attack saw bullets fired from an Audi at a BMW, as the two cars raced side-by-side through the city at night. A stray bullet flew through the front door of an "entirely innocent" family's home and landed on their hallway stairs.
