Topeka ? An eight-month investigation has led to charges against 20 people allegedly involved in manufacturing and distributing methamphetamine in southeast Kansas.

Attorney General Steve Six’s office announced Wednesday that prosecutors from its office joined with 13 other law enforcement agencies involved in the drug sweep Tuesday. The arrests were made in Chanute, Iola, Stark, Paola and Fort Scott.

Seventeen of the 20 people charged were arrested Tuesday. Two men arrested last week were included in the anti-meth operation and charges are pending against another man.
