During the visit, three people were seen leaving the back of the building and were detained by officers.
Inside the premises, police found more than 1,500 plants which were seized along with cultivation equipment.
UK Power Networks also attended to help make the scene safe, following concerns the electricity to the building had been tampered with.
Three men, aged 33, 43, and 48, have been arrested on suspicion of cultivating cannabis and abstracting electricity and taken into custody while enquiries continue.
