A woman was arrested and drugs, ammunition and firearms seized when police served three search warrants in Alexandra and Cromwell yesterday.

Sergeant Derek Ealson said the three warrants were executed in relation to the supply of methamphetamine by people linked to organised crime groups in Christchurch and Invercargill.

At two of the Alexandra addresses, police located methamphetamine, items used in the supply of methamphetamine, meth utensils, ammunition and a firearm.

A 37-year-old local woman is due to appear in Alexandra District Court on June 29 on methamphetamine and firearms charges.

Sgt Easton said enquiries are continuing and further arrests are likely.

“Police take our role in preventing the harm caused by illicit drugs incredibly seriously, and work incredibly hard to hold offenders to account,” he said.

“Similarly, we also work hard to make sure that people suffering harm from drug use get the help that they need by referring where appropriate to agencies that can help.”
