Three people have been arrested following a series of drugs raids in a major police operation that has been six months in the planning.

A 39-year-old man, another aged 43 and a 42-year-old woman were arrested after officers searched addresses in Dewsbury, Liversedge, Batley, and the Crossgates and Meanwood areas of Leeds.

Cannabis with a street value of about £300,000, as well as £60,000 in cash, designer jewellery and forged documents were taken from the addresses, West Yorkshire Police said.

All three people were arrested on suspicion of the supply, production and cultivation of cannabis and were bailed pending further inquiries.

Officers from West Yorkshire Police's Organised Crime Group and Operations Support Division executed search warrants at five addresses.

Detective Chief Inspector Ingrid Lee, of West Yorkshire Police's Crime Division, said: "This operation has been six months in the planning and we are pleased that the actions of our officers this week have taken a large quantity of drugs off the streets as well as closing down the means for their production.

"The operation is further proof of the seriousness with which our dedicated officers tackle drug crime."
