Neighbours worried about the influence of drugs in their city estate were shocked but relieved to see a police raid on a cannabis factory unfold like a "CSI show".

Officers stormed a home in Knowland Grove, in the Marl Pit estate, at 6.45am on Wednesday and found 67 large cannabis plants growing.

The drug factory also had lighting, electrical and ventilation equipment for the mature cannabis plants, leading to a 42-year-old man pleading guilty to producing a controlled class B drug in court.
