Four people have been arrested after three cannabis farms in Doncaster were shut down by police.
About £300,000 worth of drugs were seized following raids at addresses in Wheatley, Hyde Park and Cantley on Tuesday.
South Yorkshire Police said they found “significant and elaborate cannabis set-ups” in all three properties.
Three men and a woman were arrested on suspicion of drugs offences while the men were also held on suspicion of immigration offences, the force said.
