Police in Suffolk have partnered with a specialist team in London in continued efforts to prevent drugs being brought to the county.
Under the name Operation Orochi, officers in the county are analysing data from the phones of class A dealers brought into custody.
Any information garnered is then shared with the Metropolitan Police, in the hope they can find the source of the drugs.
Detective Chief Superintendent Eamonn Bridger said the sharing of intelligence should lead to "fast-time investigations".
He added: "It means that we’re in a strong position to charge and remand the controller of the drugs line on the day of arrest, before they have an opportunity to pass the drugs line to an associate,effectively shutting it down."
In one example of the operation working, last week two properties in Ilford and Margate were searched following the arrest of two men from Haverhill.
Those searches led to the arrest of two men - Maverick Dwyer, 25, of Alder Walk in Ilford and Christopher Prosser, 32, of no fixed address - who have both been charged with conspiracy to supply class A drugs.
According to Suffolk Constabulary, the offence related to drug dealing in Haverhill between July 2019 and May 2020.
Both men were remanded into custody when they appeared before Ipswich Magistrates’ Court on Friday 29 May.
