Three “persons of interest” have been questioned by investigators after a meth bust in Randolph County.

Authorities say meth making materials and a substance they believe to be meth were seized yesterday from a home in Percy.

Meth-making materials were also found near a home in Sparta.

Police departments from Sparta, Steeleville, Coulterville, and the Illinois State Police Methamphetamine Response Team aided in the investigation.
