12 arrested over NSW drug supply ring

A drug-supply ring across western Sydney and the NSW Southern Highlands has been smashed with police arresting 12 people as part of an ongoing drug-supply investigation.

Officers from Strike Force Trinculo carried out searches of seven properties on Tuesday morning. Methamphetamines, poker machines, stolen goods, a replica pistol and cash were seized, police said.

The youngest charged was a 17-year-old boy, and all but one of the 12 men and women will face local courts on Wednesday, police said.
