Cleveland Police have discovered a large cannabis farm - containing almost £1m worth of cannabis - at a property on Stockton High Street.
Officers from the Operational Support Unit and the Hub Intelligence Team made the discovery on Monday morning.
1200 cannabis plants were recovered from four floors and 12 rooms of the premises which has an estimated street value of £960,000.
Two people, aged 19 and 50, have been arrested on suspicion of drugs offences and remain in custody.
A Cleveland Police spokesperson said: “Today we have confiscated nearly a million pounds worth of drugs from our streets.
“Drugs are a blight on our society and cause misery in our communities.
"This cannabis farm was clearly organised and highly sophisticated. Criminal activity such as this is nothing but detrimental to people’s lives.
“We hope today’s result has a positive impact on our communities and shows people that as a Force we will do everything we can to rid drugs from our area.”
