Over the past week, proactive work by Hamilton Police has resulted in locating two other wanted offenders and the seizure of additional methamphetamine, money, and firearms.

"This is a great example of the work Police are doing to keep our communities safe by noticing suspicious behaviour and removing drugs and illegal firearms out off the street," says Senior Sergeant Leo Belay.

"Hamilton Police have laid a multitude of charges relating to drugs, money and firearms from offenders and those who are identified as gang members or are associated with gangs.

"Thanks to members of the public reporting suspicious behaviour, Police can respond and reduce the ongoing harm to the community."

Senior Sergeant Leo Belay says if you notice suspicious behaviour or activity happening call 111 immediately, and 105 if it is after the fact.

Information can also be reported to Police anonymously on Crimestoppers on 0800 555 111.
