Police arrested a man on suspicion of drugs offences after finding what they believed to be cannabis plants at a house in Chesterfield.
Officers searched the property, in Oakamoor Close, on Thursday, April 24 and found a number of suspected plants inside.
A 24-year-old man was arrested on suspicion of producing a class B drug and has been bailed pending further enquiries.
The arrest comes during a four-week Derbyshire Constabulary campaign to encourage members of the public to report suspected residential cannabis farms in their community.
Residents are being urged to be on the lookout for telltale signs of cannabis farms, which include:
A strong and sickly sweet smell that may be covered up with creosote or paint;
Cannabis growing equipment such as lights, fertiliser and cables being moved into or out of a property;
Constantly covered or blocked off windows at the front and rear of a property;
Visitors at unsocial hours and few sightings of the occupants of the house;
Strong and constant lighting throughout the day and night;
High levels of heat and condensation, visible on the windows;
The constant buzz of ventilation.
If you have any information related to suspected drug production, call Derbyshire police on 101.
