A cannabis farm valued at £200,000 has been discovered by a police helicopter in Gravesend.

Patrols had discovered a small patch of marijuana plants growing on Dering Way however evidence suggested there may be more on the premises.

A police helicopter conducted a search and subsequently found the farm located on marshland.

The plants were destroyed at the scene.

Detective Sergeant Aaron Watkin said: "Some of these plants were eight feet tall and have obviously been grown with the intention of distributing drugs on the street."

"The estimated value of this growth is around £200,000. We are currently following up lines of enquiry to identify those responsible and I would appeal to anybody who knows anything about this cultivation to come forward."
