Five suspects are in custody as a methamphetamine lab, in Kimball Township, has been closed down. That, thanks to the work, this week, by the St. Clair County Drug Task Force and other local law enforcement agencies. Officials say a traffic stop on Tuesday, in Port Huron along Union and 15th Street, saw the DTF seizing drugs and arresting two people who led officers to the meth lab along the 52-hundred block of Griswold. DTF agents seized meth, lab equipment, and other drug materials. The suspects are from Riley, Kimball Townships, and Port Huron. They're at the St. Clair County Jail and are expected to be charged with several drug offenses.
