A ST COLUMB man charged with six Class A drug offences, including the alleged supply of heroin, has been sent to Truro Crown Court in custody.
Alan Dean, of Trelawney Parc, was denied bail after appearing in custody before District Judge Cadbury at Bodmin Magistrates' Court on Thursday.
The 47-year-old was arrested the day before as part of a major countywide drugs raid by Devon and Cornwall Police.
Dean is charged with supplying 6.61g of heroin to 'Liam' on May 8; 0.98g on May 13; 1.66g on May 21; 0.98g on May 22 and offering to supply quantities of the drug on May 3 and 22.
He is due to appear at the Crown Court for a hearing on July 5.
Also arrested as part of Operation Minnis was a 34-year-old St Columb woman, on suspicion of supply of heroin. The woman has been bailed until July 12.
Newquay and St Columb Major inspector, Dave Meredith, said: "This series of drugs warrants has had a significant impact on the supply of heroin, a Class A drug, across Cornwall.
"The supply and use of heroin has had a devastating effect on communities across the country.
"Heroin is one the most destructive controlled drugs available on the streets, and I would encourage anybody with information on this drug to contact the police on 101 or anonymously via Crimestoppers on 0800 555111."
At around 8am on Wednesday, police and Trading Standards executed several warrants in St Austell, Newquay and Bodmin.
More than 80 officers carried out a co-ordinated response to the suspected supply of drugs and handling of stolen goods based on gathered intelligence collected in the areas over a "significant" time.
Officers used a variety of specialist methods of entry to gain access to the targeted premises and were supported by specialist dog handlers.
A police spokesman said: "In total police identified more than 50 offences relating to possession of drugs, supply of Class A and B drugs, handling offences and money laundering offences.
"Restraining orders are being sought against a large amount of cash and money in bank accounts. Quantities of drugs seized include (subject to forensic tests) heroin, amphetamine and cannabis."
