WATCH: Huge cannabis farm discovered in old casino

Footage has shown the moment one of Northamptonshire's largest ever cannabis factories was discovered across four floors of an old casino.

Police uncovered thousands of plants during a search of the former Aspers building on Commercial Street in Northampton on Thursday morning.

They used chainsaws to gain access to the building, with the doors being bricked-up and rooms reinforced with steel.

Sgt Rodney Williams said taking the plants out of production was "going to make a massive difference to the drug supply chain here in Northampton, and possibly in the UK".

Police have arrested and charged a man with one count of producing a controlled drug of Class B - cannabis.
