A call for suspicious activity at a rural residence in Bartlow Township in Henry County this past week, has led to the discovered of a methamphetamine lab.  Henry County Sheriff Mike Bodenbender reports information led them to work with Wood County law officers in the case.  Items used in the production of meth were located at an abandoned house in Richfield Township of Henry County.   The Bureau of Criminal Identification and Investigation was called-in to process evidence, and to secure any items of illegal drugs.  Charges are pending in the case; but no arrests have taken place at this time.
