More than 400 cannabis plants were confiscated in North Leeds this week after police raids on two cannabis farms.
Officers confiscated 300 plants from a farm in Chapel Allerton, and a further 110 plants from a farm in Chapeltown after taking out a thermal imaging camera.
Police enquiries are on-going and they are appealing to anyone who has any information about the farms to call Crimestoppers anonymously on 0800 555 111.
