CANNABIS worth over a quarter of a million pounds was seized from a house in Accrington on Tuesday.
The substantial quantity of drugs was found after police raided the Avenue Parade property.
The drugs, weighing around 150kg, are yet to be forensically tested but are believed to be cannabis resin.
Detective Inspector Mark Winstanley from Blackburn CID said: “This is a seizure of a huge amount of cannabis resin which is likely to have a significant street value.
“An investigation has been launched to find out where this cannabis has come from and how it was planned to be sold on.
“A lot of our information about drug-related activity does come from the public and I would urge them to continue to come forward and let us know of this type of activity.”
