Police remain on guard across Tamaki Makaurau as they try to defuse tensions after a spate of drive-by shootings. There were seven on Tuesday night and another two last night. The shootings are believed to be linked to a turf war between the Tribesman and its former feeder gang, the Killer Beez. Police are now attempting to restore a truce between the gangs. Susie Ferguson spoke to the Police Association's president Chris Cahill.
