Police raided a cannabis factory with a crop potentially worth around £95,000.

Officers attended the address in Willow Way, Potters Bar, and found more than 230 cannabis plants along with highly hazardous butane gas canisters which are used to make cannabis oil.

There was also evidence of previous harvests suggesting the property has been used to grow cannabis plants for some time.

A 35 year old woman from Potters Bar and a 31 year old man from Potters Bar have been arrested on suspicion of being concerned in the production of a controlled drug.

Both have been released under investigation whilst the investigation continues.

Hertsmere Chief Inspector Steve O’Keeffe, said: “This was a great example of partnership working. The Scorpion and Operational Support Group assisted, which helped us to make these arrests. This looks like it was a well set up operation that would likely have put large amounts of illegal drugs on to the streets of Hertfordshire.

“These kinds of factories use large amounts of water and electricity and often these are syphoned from other people’s supplies and can cause damage or fires to surrounding properties. Everyone needs to be alert to these types of factories which can be set up relatively quickly and may only be detectable by those living close who may notice unusual behaviour from the occupants.”

Police urged people to look out for the signs of homes being used as cannabis factories.
