"This month of action has been a great opportunity to target organised crime gangs that are running cannabis production sites across the county," said Detective Chief Inspector Dave Skarratts, from Hertfordshire Constabulary’s Local Policing Command.

"We’ve seized thousands of plants along with growing equipment, as well as arresting many of those involved in the production and distribution of cannabis.

"We conducted more than 30 warrants, which is going to make a major impact on cannabis supply and organised crime groups in Hertfordshire.

"We take a very proactive approach, working with our partners in other forces and national agencies to target these crime groups.

"This operation also provides a chance to raise awareness of cannabis farms, which can appear anywhere in the county and pose a danger to those living nearby, either as a fire or electrical risk or from anti-social behaviour and violence that is associated with this type of crime."
