Tens of thousands of pounds of suspected Class A drugs have been seized by police.
Officers made the initial discovery after stopping a van on Westfields, Castleford, at around 2pm on Monday.
A substantial amount of suspected drugs was found in the vehicle and a 58-year-old man was arrested on suspicion of possession with intent to supply a Class A drug.
Later that day, police searched a house on Westfields and discovered a large amount of suspected Class B drugs and money.
A 45-year-old woman from Castleford and a 45-year-old man from Leeds were arrested on suspicion of possession with intent to supply drugs. All three people have now been bailed.
Det Insp David Rogerson, of Wakefield CID, said: “We are continuing enquiries after officers recovered significant amounts of what are suspected to be Class A drugs from a van and a house following an intelligence led operation.
“Taking drugs off our streets continues to be a priority for the police.”
Anyone with information should call Wakefield CID on 101 or Crimestoppers, anonymously, on 0800 555 111.
