Twenty-one people have been indicted on charges of distributing drugs throughout Kansas.

The indictments were unsealed Thursday after investigators made arrests and served 32 search warrants Wednesday in Topeka, Great Bend, Salina, Lawrence, St. Marys and Kansas City, Kan.

The indictments allege that the defendants imported methamphetamine and other drugs from Arizona and sold them in three of the cities where the warrants were served — Topeka, Great Bend and Kansas City, Kan.

U.S. Attorney Lanny Welch said in a news release that the investigation began in the summer of 2008. It resulted in the seizure of more than $600,000 in cash, 10 pounds of methamphetamine, half a pound of cocaine, 20 vehicles and 30 firearms and ammunition.
