More arrests are expected after a methamphetamine bust in northeast Iowa. 41-year-old Richard Keith Jochem (JO’-kum) of Hazelton is charged with possession and the manufacturing of meth.

He says the public has to report things if they see something going on.Jochem is being held at the Buchanan County jail.
