Twenty suspected cannabis plants were seized by police after a raid on a house in Leyland.
Officers stormed a house on Durham Close and found three mature plants, a harvested plant and a number of seedlings in the upstairs bedroom and attic.
PC Steve Gallery, community beat manager for Wade Hall, said they executed a warrant under the Misuse of Drugs Act based on information received by members of the public.
He said: “This is another example of us working with communities to tackle their concerns.
“We carried out this warrant as a result of information we received from residents. We do act on all intelligence relating to drugs and I would urge communities to continue to tell us about any suspicious activity.”
The raid happened at around 4pm on July 6.
A 46-year-old man was arrested on suspicion of producing cannabis and abstracting electricity.
He has since been released from custody pending further enquiries.
