A second wave of drugs raids took place in Preston this morning with four people arrested on suspicion of dealing class A drugs.
Two men aged 19, an 18-year-old and a 17-year-old youth have all been arrested from the Avenham area of the city following dawn raids on four addresses this morning.
This brings the total of arrests to 13, with nine people currently charged for drug related offences after similar raids earlier this week.
Operation Nimrod struck Preston on Monday, March 24 and today, with around 100 officers from across the county, including support unit officers, dog patrols, and CID staff taking part in the operation for the second time this week.
Operation Nimrod is an intelligence-led operation that is targeting drug crime across the force and has involved months of evidence gathering on alleged drug dealing in Lancashire.
The types of drugs involved are believed to include heroin and crack cocaine.
Ch Supt Pete White, Divisional Commander at Central Division, said: "We are committed to taking Class A drugs off our streets and the message to drug dealers is simple: seek treatment or we could be knocking down your door next."
