7News reports South Australian police are quickly unravelling a sophisticated Albanian drug syndicate, after multiple raids on houses in Adelaide's southern suburbs.

Thursday morning officers from the specialised drug taskforce, Operation Mantle, raided two neighbouring houses at Sturt and found a complex hydroponic cannabis set up.

Thursday afternoon a third house was raided, and a similar hydroponic set up was dismantled.

Around thirty plants were seized.

All of the homes were unoccupied and neighbours have told 7News they rarely saw people on the property.
