Police have raided and closed down a second cannabis factory in Keighley in a fortnight.

The Bradford District Drugs Team recovered about 450 suspected skunk cannabis plants from an address in Prior Street at 11pm yesterday.

Police said they were alerted by the landlord of the property.

Officers are now working to trace the people responsible for running the suspected cannabis factory.

Detective Inspector Neil Benstead, of the Bradford District Drugs Team, said: "I would ask landlords to remain vigilant and to regularly check their properties for any suspicious activity. Be wary of any tenants wanting to pay their rent in cash, away from the property.

"It is in the landlord's best interests to report any suspicions to police. If a property is being used to cultivate cannabis, it will have been extensively damaged."
