Police seized 1400 cannabis plants grown in a hydroponic lab across six properties and arrested five Vietnamese nationals in the Hunter Valley on February 14.

About 8am on Wednesday, authorities raided homes in Raworth, Tenambit, Heddon Greta, Aberglassyn and Chisholm and discovered rooms with fake walls where the plants were being grown and cultivated.

Police said the drugs are worth approximately $2.8 million. Two of the men arrested are allegedly “illegal immigrants.” Credit: NSW Police Force via Storyful
