Officers swooped on five addresses throughout Telford carrying out drugs warrants. They detained a 37-year-old man from Arleston.
He was arrested on suspicion of cultivating drugs, human trafficking and modern day slavery. He currently remains in custody at Telford.
Several items were seized during the operation, including mobile phones and other items believed to be linked to drug offences.
Detective Sergeant Natalie Arrowsmith said: "This was a large scale police operation fuelled by intelligence that was acquired during the execution of other warrants in November 2020.
"We will continue to tackle the supply and cultivation of drugs in the area. Modern day slavery is an extremely harmful and ever present issue and the force will continue to carry out operations such as this to protect vulnerable people and keep the community safe."
