A dramatic drugs raid at a derelict former sweetshop in the heart of a Worcestershire town has led to the discovery of a massive 600 plant cannabis grow.

Two arrests were also made as officers smashed their way into the former shop at 4 High Street in Droitwich at 7am today (Wednesday) to find the sophisticated grow, capable of making nearly £500,000 on the street.

A 20-year-old man and a 39-year-old, understood to have been living at the property, were cornered and detained in the overgrown back yard as they attempted to escape.

Both were arrested on suspicion of the production of cannabis, a class B drug, and are in custody at Worcester Police Station in Castle Street.

The estimated value of the cannabis, if sold in street deals, was estimated by police at £491,000. 

Every single plant will now be catalogued and destroyed.

Officers from West Mercia Police smashed their way inside using an enforcer (a metal battering ram) and a rabbit, a hydraulic entry device, discovering plants at various stages of maturity and in nine rooms spread over three floors. 

The warrant was a joint effort between Droitwich Safer Neighbourhood Team, who gathered intelligence based on concerns raised by the community, and the Neighbour Crime Fighting Team (NCFT) who secured a court warrant.

DI Dave Knight of West Mercia Police said: "Whatever your view is on cannabis the facts around illegal cannabis production and consumption are clear, that it feeds organised crime and also facilitates modern day slavery. We will do all we can to remove these cannabis factories from the West Mercia Police area."

A heavy smell of cannabis still hung in the air as shoppers walked along the High Street - and it was the smell that alerted the public.

It is understood the grow was powered by abstracted electricity which had to be capped off by workers from the National Grid before it was cut altogether which involved digging up the pavement outside.

PC Warren Edmunds of the NCFT said cannabis grows in houses typically involved between 50 and 150 plants and this grow was the largest NCFT had dealt with since it was formed last July.

Sgt Shaun Blackshaw described the grow as an 'industrial-sized', comparable to the sort ordinarily found in larger warehouses rather than houses or shops.

For example, nearly 500 plants were discovered in a warehouse in Hanbury, near Droitwich in February.

Sgt Blackshaw said officers would be at the scene well into the evening.
