Clinton Township police have made contact with a man they say could be involved in dropping a letter that contained a suspicious powder in a drop box outside a Michigan Department of Human Services building in Mount Clemens.

An employee inside the building was taken to the hospital on Monday as a precaution after opening the letter.

In a statement, the DHS said a hazardous materials team from Clinton Township was called in to test the substance and determined it was an irritant. But the employee was checked out at the hospital and will be fine.

The Local 4 Defenders have learned that investigators executed a search warrant at a home in Harrison Township, near Gratiot and Joy Road, in connection with the case.

Sources said investigators talked with a man at the home but he was not arrested. The case continues to be actively investigated.
