Nine people were arrested in Hayle this morning after police conducted an early morning drug bust.
More than 50 police officers were involved in the dawn raid.
Eight warrants were executed in Operation Calf, resulting in nine arrests with regards to drug trafficking offences.
During the operation police recovered what they believe to be a “trafficking amount” of heroin, several items suspected to be stolen property and thousands of pounds related to money laundering offences.
Detective Inspector for west Cornwall, Pete Simms, said the operation was a success.
“We have had a good operation. We conducted the operation as a result of rising crime and drug activity in the Hayle area which was brought to the attention of the neighbourhood team. We have been monitoring the drug activity. We wanted to arrest people, bring them in and put the evidence to them.”
DI Simms said the force have been liaising with the Crown Prosecution Service and believe four or five charges will be made later today in relation to drug trafficking offences.
Operation Calf, which police have been preparing for since December, was conducted at 7am this morning.
Fifty-four officers from across Cornwall were drafted in to execute the operation.
DI Simms added: “A number of officers came in from rest days to support the operation. The Hayle mayor was present. We will be participating in searches for some time and interviews will be conducted until this evening.”
