Cannabis with an estimated street value of between £750,000 and £1 million has been seized by police in Northern Ireland.
Two men aged 36 and 21 have been arrested and are helping police with their inquiries.
Plants, cultivation equipment and drugs paraphernalia were seized when officers from the Police Service of Northern Ireland (PSNI) swooped on a suspected cannabis factory in Portadown. The items have been removed for forensic examination.
Detective Chief Inspector Stephen Wright said: "Officers on patrol in this area noticed a smell of cannabis and their subsequent inquiries led them to this cannabis factory.
"We are pleased to have removed this amount of cannabis from circulation in our community and I would urge anyone who has information in relation to drugs to contact us immediately on 101."
Earlier this month the PSNI launched "scratch and sniff" cards to help the public recognise the smell of growing cannabis.
The cards contain an element that replicates the smell of cannabis in its growing state, which smells different from when it is being smoked.
Mr Wright added: "We hope these cards will help to educate and inform about how you can spot and detect cannabis factories."
