FIREFIGHTERS responding to a 999 home call were shocked to discover a nursery of cannabis plants.

The Oxfordshire Fire and Rescue crew were called to the fire in Wallingford only find at least seven large plants in the garden.

Thames Valley Police South and Vale team shared this photograph on twitter this afternoon and quipped: "If you are going to have @OxonFireRescue around for an impromptu bonfire its probably worth not having these on show!

"#Cannabis is illegal."

The team said an investigation has been launched.
