Essex Police has uncovered a “professional” cannabis factory in Brick End after raided a industrial unit.

Officers from the force’s Braintree and Uttlesford Community Policing Team obtained a warrant to search the building.

They applied for the search warrant after a report of a smell of cannabis coming from the large unit.

Police raided the site on Monday, October 30, and found multiple rooms where cannabis could be grown.

Around 120 plants were discovered, along with a substantial amount of cannabis in the process of being dried out, a force spokesman said.

No people were found at the site, but investigations are ongoing.

Inspector Mick Couldridge said: “This is a really significant find and the site has the potential to be used to cultivate a large amount of drugs.

“The set-up looks very professional and our officers are likely to remain on site throughout today [Tuesday] to dismantle the growing equipment.

“It is now important that we identify who’s responsible for growing this cannabis, so if you have any information about it I need you to come forward.”
