Detectives arrested a Vietnamese man who fled from the scene after police discovered a large-scale cannabis farm in St Helens.
Officers raided a house in Charnwood Street, St Helens, at around 8am today (Friday).
The man is still being questioned by detectives at St Helens police station.
A Vietnamese man ran out of the property as officers began their search but he was arrested in a nearby house on suspicion of cannabis cultivation and abstracting electricity.
Local officers searched the house and discovered more than 200 plants in several rooms within the premises.
The house was sealed off and specialists from the force’s cannabis dismantling team attended later to remove the plants and secure other evidence.
Insp Steve Brizell said: “This was a sophisticated set up involving cleverly by-passed electricity and a complex lighting and irrigation system.
“It was also a particularly large cannabis farm for a small terraced house. Cannabis farms of this size can yield thousands of pounds of drugs for the criminals running them and this money in turn is reinvested by criminal gangs in Class A drugs and weapons which cause immense damage on the streets of Merseyside.
“Community information is key to us discovering cannabis farms hidden away in our residential areas and I would urge people to continue to report their suspicions to us or Crimestoppers so that we can take decisive action like we have done today.”
Anyone with information can call Merseyside Police on 101 or the confidential Crimestoppers line on 0800 555 111.
