Authorities say they used a Shelby Township gas station and a store in the drug enterprise. "Approximately $20,000 in cash, a large amount of spice and K2, which is packaged, also in crates and boxes in the back," said Shelby Township Police Chief Rolland Woelkers.

In June, Shelby Township residents staged a large protest at a Citgo gas station because it sold K2 and other synthetic drugs. At the time, it was still legal. When it became illegal, police began an investigation.

"We send people in and they make buys. Based on the buys we get search warrants, and that's basically how most narcotic investigations are conducted," said Woelkers.
