A large cannabis farm has been discovered at a house in Bolton. 

Greater Manchester Police said officers in Halliwell discovered a cannabis farm in a house yesterday. 

Writing on the GMP Bolton Central Facebook page, officers said: "Halliwell team PC Bolton and PCSO Thornley whilst on enquiries stumbled upon this cannabis farm. Front room, two bedrooms and the loft full of cannabis plants."

A spokesman for Greater Manchester Police added the plants were discovered at a home on Shepherd Cross Street. 

No arrests have yet been made, but police are following 'several lines of enquiry'. 

Since 2009, cannabis has been classified as a class B drug under the Misuse of Drugs Act 1971 - which means it is illegal to have for yourself, give away or sell.
