A South Australian man with bikie links will face court following the discovery of a cannabis drop in an underground bunker.
Police raided a house in Yatala Vale on Friday morning and allegedly found a hydroponic cannabis crop in a buried shipping container under a shed.
Pictures show a manhole in the floor of the shed leading to the crop and officers also found a further two growing rooms, uncovering a total of 30 plants.
It's alleged they also found two guns.
A 57-year-old man was arrested and charged with cultivating cannabis, drug trafficking, possessing firearms without a licence and the theft of electricity.
"Investigators believe the arrested man has links to a number of Outlaw Motorcycle Gangs, reinforcing the association of bikies with illicit drug trafficking and the unlawful possession of firearms," Detective Inspector Scott Fitzgerald said.
The man is expected to appear in Adelaide Magistrates' Court on Friday.
