In March, a youth hikoi was organised in Otangarei where residents made a stand against gangs, crime and drugs plaguing their suburb.
The suburb had been rocked recently by a number of events, including families having to move out in January as a power struggle between two rival gangs threatened to boil over.
Tensions between rival gangs Black Power and Tribesmen had the Otangarei community on high alert with local people warning each other to stay off the streets in case gang warfare erupted.
Otangarei residents were often scared to identify offenders for fear of reprisals.
