The discovery of a body in a Northern Rivers home led NSW Police to make a drug bust on Friday.

A 37-year-old man was found unresponsive and died in the home on James St at Dunoon, 12-minutes north of Lismore, at about 9am.

A commercial quantity of prohibited drugs was also found when emergency services arrived at the scene, police said.

A large amount of hydroponic cannabis and psilocybin, also known as magic mushrooms, were found.

A search warrant was then executed in the house, where equipment associated with the cultivation and manufacturing of prohibited drugs was seized, along with ammunition, and cash.

“Due to the hazardous nature and scale of the grow operations, specialist police and equipment were required to process the crime scene,” police said.

Investigations are ongoing, and a report will be prepared for the coroner.

Anyone with information is urged to contact Crime Stoppers.
