Police have carried out a series of coordinated raids across Perth in an operation targeting suburban drug dealers.

Dozens of drug warrants were executed across the metropolitan area.

Code-named 'Operation Crackdown' the raids were the culmination of months of intelligence gathered from calls to CrimeStoppers and covert police surveillance.

Dozens of arrests have been made and detectives have seized illicit drugs, stolen property and weapons.

Police say the aim of the operation is to disrupt the activities of mid-level drug dealers and their associates who are often responsible for much of the property crime committed to support drug habits.

Charges are yet to be laid but several people are helping police with their inquiries.
