A teenager has been arrested following the discovery of a massive cannabis farm at a house in Haydock.
Officers raided the Station Road property today (Friday) and found around 400 plants.
The cannabis farm would have an estimated annual yield of around £1.6m.
The plants were recovered alongside growing equipment and the electricity was found to have been illegally bypassed.

Sgt Stephanie Barcroft said: “Every single cannabis farm we seize and every arrest we make marks another step in our efforts to disrupt the activities of criminals growing cannabis in Merseyside.
“Cannabis cultivation by criminal gangs can cause serious harm in our communities and we know criminal groups involved in the cultivation of cannabis are usually involved in other serious organised crime.
“The growing of cannabis also threatens the safety of neighbouring properties because cannabis farms are a serious fire risk.
“Electricity and water are never a good combination, and fires have been caused by the crude systems put in place by the people who set up these farms.
“Our communities can help us stop these groups, who are only interested in making money, from turning houses and flats into potential death traps.
“Nobody wants to live next door to these houses and we would ask that if you believe someone is using a property for this purpose, please tell us so we can take positive action and find those responsible for setting them up.”
