A 23-year-old man has been arrested on suspicion of cannabis cultivation after officers raided a property in a county village.
The arrest followed the discovery of a cannabis factory at a house in Westfields, Easton on the Hill, last Friday (September 13).
Officers searched the property and discovered 64 young plants and 24 plants almost ready for harvest.
The man from Peterborough has been bailed pending further investigations.
