Two men have been arrested after heroin with a street value of £1.2 million and a suitcase full of cash was seized in a string of raids in Merseyside.
Officers found 12kg of the drug and around £500,000 during a search of a property in the Thatto Heath area of St Helens.
Images released by police show blocks of heroin and a black suitcase stuffed with bundles of notes.
A 52-year-old man, from Thatto Heath, was arrested on suspicion of conspiracy to supply Class A drugs and money laundering.
A second man, 56, was arrested on suspicion of the same offences after officers seized around £30,000 from his car after a search of one of two addresses in Huyton.
Merseyside Police said both have been taken to police stations to be questioned by detectives.
Detective Inspector Nick Hughes, from TITAN, the North West Regional Organised Crime Unit (NWROCU) said: "TITAN is committed to tackling the blight of drugs on our streets and has already had many successes in disrupting the supply of drugs across the North West.
"We will continue, with the support of police forces across the North West, to target those involved in the supply and distribution of Class A drugs and put them behind bars."
