Police have uprooted a cannabis farm in Sunderland after 200 plants were found at a house on Rosslyn Terrace on Monday 4 March.
No arrests have currently been made, but police are trying to trace the house's tenants who they believe may have important information about the cannabis farm.
Chief Inspector Richard Jackson said:
"The destruction of this cannabis farm once again demonstrates our ongoing commitment to tackling drug crime in Sunderland.
"It shows our commitment to removing drugs from the hands of criminals and has stopped an amount of cannabis from being distributed in our communities.
"We would encourage people to contact us if they suspect a property is being used to produce drugs.
"Tell tale signs include people arriving at unusual hours, a pungent aroma in the area, blacked out windows or bright lights coming from a number of windows throughout the night.
"I'd also like to remind landlords just how important it is for them to look for signs regarding cannabis farms. We know from previous experience that those setting up farms often pay a large amount of rent up front in cash to keep landlords away.
"It's vital landlords check on their property regularly as the damage caused to homes by the setting up a farm is often more costly in the long run.
"By working together, we can put a stop to drug offences in Sunderland."
Officers are encouraging anyone with information about drug use, or the growing of drugs in their community, to contact police on 101.
