As officers were patrolling on Wednesday they discovered a haul of cannabis worth £4.5 million which had been stashed at a building.
The police said the scent of the stash of the class B drug had caught their attention as they were passing by a storage warehouse in Oswaldtwistle, near Blackburn, on Wednesday.
Empty streets as most people have been working from home due to the coronavirus pandemic enable the police to take proactive measures in their investigations without interference.
Officers seized different types of drugs worth millions since the beginning of the coronavirus lockdown as drug traffickers were not able to conduct their activities due to restrictions.
It is believed that the seizure of cannabis on the town`s Commercial Street is one of the largest drug seizures in the UK. The police said they found several boxes with pre-packaged bags of cannabis resin and cannabis bush stashed in the storage warehouse.
Detective chief inspector Tim Brown, from East Lancashire CID, said: “This significant discovery was the result of fantastic proactive police work, initially by neighbourhood policing team officers.
“While the investigation is still at an early stage, enquiries are progressing and I would encourage anybody who has seen unusual activity around this site in recent months to contact police.”
The police said that no arrests had been made so far as they are still investigating and trying to find out how the drugs got there.
Clive Grunshaw, Lancashire’s police and crime commissioner, said: “The crucial work carried out by Lancashire officers in keeping drugs off our streets achieves real results like this that make our communities safer.”
Officers urged anyone with information to call them.
