Three gang associates are facing a raft of drug and firearm charges.

The arrests come as Cambridge Police investigate the supply and manufacture of methamphetamine, as part of Operation Cobalt.

Three men, aged 32, 34 and 55, have been arrested over the past four weeks following a number of successful search warrants.

All are appearing in the Hamilton District Court – the 34-year-old man and 55-year-old man are due to appear today, and the 32-year-old man is due to appear on Friday, February 24.

Police seized three ounces of methamphetamine, a methamphetamine lab inside a horse float, over $15,000 cash, firearms and ammunition during the search warrants.

'This is a fantastic result which has been achieved through good Police work by local staff and community support," says Sergeant Ben Joll.

'We hope these arrests provide some reassurance to the Cambridge community that we are committed to making our communities safer from the influence and harm caused by gangs and their criminal activities."

'These arrests will make an impact on the harm caused by drugs in our community, the consequences of which reach much further than the individual user.

'We have no tolerance for this sort of offending and urge anyone to contact Police if you have concerns about or suspect drug activity in your neighbourhood."
