Sharp Rise In London Cannabis Factories

Children are being trafficked to the UK to work on cannabis farms - stats show 850 have been shut down in London last year.

It's a rise of 175 per cent over the last 2 years but police say it's down to more officers focusing on the problem.

A report by the Association of Chief police Officers reveals the MET's uncovered over one-thousand-four hundred of the biggest factories in the country since 2008.
