A teenage boy and two young men have been charged in connection with a string of targeted home invasions, arsons, and shootings that have terrorised Melbourne's north-west suburbs since early January, with sources linking the group to a sprawling organised crime syndicate operating from offshore bases and across Australia.

The arrests followed coordinated raids on four properties in the area, including sites in Moreland, Broadmeadows' Lahinch Street, Roxburgh Park's Watersedge Way, and Taylors Hill's Synergy Court. These actions targeted a series of seven violent episodes that struck homes in a pattern of escalating aggression.
