The St. Petersburg Police Department held a news conference on Wednesday detailing a "major spice roundup" in the downtown and 34th Street N areas.

The roundup consisted of undercover and uniformed police officers targeting buyers, sellers and businesses found violating city and state ordinances governing synthetic marijuana.

Officers distributed educational pamphlets about Spice to businesses and the public in the targeted areas.

Officers believe convenience stores are selling the packets. Those buyers are then boarding buses to sell the synthetic drugs, by the joint for a huge profit in Williams Park.

Yesterday police arrested 20 individuals and fined two convenience stores.  Frog Eyes Smoke Shop located at 6040 4th St. N. received a $21,500 fine and Mario's Meat Market 3701 5th Ave. N., received a $23,000 fine.
