Drugs with a street value of £6.7m have been recovered during the biggest ever seizure operation in Nottinghamshire.
Ch Supt Moyes said he had never seen a drugs haul on this scale
Officers carried out the raid in Ruddington, near Nottingham, where they found a variety of drugs.
They seized 64kg of heroin worth about £6.4m on the street, 54,000 ecstasy tablets worth £270,000 and amphetamine worth about £50,000.
Two men and a woman were arrested and released on bail pending enquiries, Nottinghamshire Police said.
'Scourge of streets'
Divisional commander Ch Supt Pete Moyes said: "I have never, in my entire career, seen a drugs haul on this scale.
"These drugs are the scourge of towns and cities throughout the country. All of this was destined for the streets.
"It is extremely satisfying to know that we have disrupted a major supply in such a dramatic fashion."
The drugs are now undergoing forensic examinations and are being held at a secure, undisclosed location.
