Two teenagers have been arrested after police discovered a cannabis factory in a Clackmannanshire home.
Officer seized about 500 plants with an estimated street value of £240,000 after the raid at the house in East Burnside, Dollar, on Friday.
Central Scotland Police said the find highlighted that such factories could be "literally on your doorstep".
The teenagers, aged 16 and 18, are expected to appear at Alloa Sheriff Court later.
The force is running a campaign to crack down on domestic cannabis cultivations.
Signs that a house is being used as a factory include blacked-out windows, a sweet and distinctive smell and a low level hum or loud buzzing sound.
Det Insp Charlie Mitchell said the houses may emit lots of heat and are often visited late at night or in the early hours of the morning.
Visitors to the premises may also bring in building supplies and gardening equipment, he added.
