Arizona became the center of an international drug bust Tuesday, linking 20 Valley meth labs to a chemical supplier in Scotland.

Scotland Yard was involved in the investigation. Investigators went after a company that turned over their client list. There are 20 homes in Arizona that had links to this online drug operation.

At one location near McClintock and Baseline in Tempe, one suspect sat in handcuffs while undercover detectives used rubber gloves to take inventory.

This investigation took two years. Police say the suspects logged on to the website of a Scotland internet company and bought chemicals used to make meth.
