Police have seized drugs in three unrelated searches of addresses in north-east Derbyshire.
Two men were arrested after cannabis and a number of other controlled drugs were found at a property on High Street in Clay Cross on Saturday.
Five cannabis plants were seized from the garden of a house on Bunyan Crescent, Stonebroom, on Monday.
Cannabis plants were also found at a house on Fir Tree Avenue, Stretton, earlier this month.
A 20-year-old man was given a caution for the possession of cannabis at the Stretton property.
Following the Clay Cross search, a 22-year-old man was arrested on suspicion of possessing cannabis and given a caution.
Another man, 51, was also arrested on suspicion of possessing controlled substances and has been bailed pending the results of an examination of the substances seized from the house.
Police said they were yet to speak to the occupant of the house in Stonebroom.
