Police discovered an illegal cannabis farm in Leeds after it caused part of a road to collapse.

Cannabis growers had tunnelled out under the road to connect to a mains electricity supply to power lights and hydroponics.

Insp Richard Coldwell said: "This was quite an extreme incident where the road had actually began to collapse as a result of the tunnel from the cellar to the mains supply."

The operation led to the discovery of more than 1,000 Cannabis plants in the Headingley area of Leeds.

Two people have been arrested in connection with the matter and are currently in custody.
