Two men who ran a huge Breaking Bad-style amphetamine factory will spend longer in prison after a court found their sentences to be "unduly lenient".
The drugs lab was one of the largest amphetamine factories ever found in the UK and was capable of producing 400 kilos of amphetamine per month, worth £2 million at wholesale and up to £10 million at street level.
Keith Davis, 56, from Buckinghamshire, underwent chemistry training to enable him to operate the huge site. Andrew Gurney, 51, from Birmingham, known as ‘The Geek’ due to his specialist electrical installation and plumbing skills, converted what had been a double garage outbuilding into the drugs lab.
