Officers recovered large quanties of cannabis and cocaine during two separate operations in Lanarkshire.
Police searched a house in Underwood Road, Newmains, at 10.15pm on Wednesday and recovered cocaine worth £80,000 and cannabis worth £75,000. Two men, aged 30 and 34, and a woman, aged 30, were due to appear at Hamilton Sheriff court today.
In a separate operation, officers searched a house in Glendale Avenue, Airdrie, at around 12.30pm on Wednesday and recovered cannabis worth £15,000.
A four figure sum of cash was also seized.
A 42-year-old man appeared at Airdrie Sheriff Court yesterday in connection with the raid. Detective Chief Inspector Pat Campbell, of Motherwell Police Office, said: "These operations show we are absolutely determined to rid our communities of serious and organised crime.
"We will continue to seek out anyone involved in the sale and supply of controlled drugs in our local areas.
"I would encourage members of the public to remain vigilant and continue to report any suspicious activity to their local police office."
Earlier this month officers recovered cannabis plants with a street value of £750,000 from a house in Kirkintilloch.
Officers also discovered an extensive heating and lighting system which was being used to ensure the growth of the plants.
Two men, aged 39 and 40, were arrested and appeared in court.
