Three people have been arrested on suspicion of producing cannabis at a house in Ely after two police officers discovered a factory while walking their beat.
South Wales Police said police community support officers Will Evans and Rachel Lee were on foot patrol in the Mill Road area of Ely on Saturday when they smelt something suspicious.
They followed the scent to a property in Cowbridge Road West, into a communal hallway and to a flat where the smell seemed to be coming from.
At around 3.30pm, they found a number of mature cannabis plants and a box of cannabis bush in the bedroom and attic.
Three men – two aged 29 and one aged 34 – from Rumney, St Mellons and Trowbridge were arrested on suspicion of production of cannabis and officers dismantled and removed all the equipment that was found, along with the cannabis.
Sergeant Jayne Hill from Ely Police Station said: “We will always take positive action where there is information to suggest drugs are being used, cultivated or supplied here in Ely.
“Cannabis factories are not only illegal they also can also pose a fire risk to neighbouring properties.
“Our PCSOs are constantly on patrol in the community where they can play a vital role in keeping people safe while also tackling anti-social behaviour and crime.”
Anyone with information about the use, supply or cultivation of cannabis should contact South Wales Police on 101 or Crimestoppers anonymously on 0800 555 111.
