The St. Clair County Drug Task Force, and several other agencies, raided four homes late last week seizing more than $20,000 of methamphetamine, $400 in heroin and other illegal narcotics. Agents also recovered several firearms including an AK-47. One raid was in Marysville and the other three were in Detroit with three men arrested and lodged in jail. In the Marysville raid Friday night, DTF agents recovered $2,900 worth of meth, handguns, marijuana and a large amount of cash. Agents say they are working to cutoff the large pipeline of drugs coming to the Thumb area from Detroit.
