TRENTON, Mich. (WXYZ) — A Secretary of State branch in Trenton is closed after a man allegedly made threats Monday morning.

Police say the man was trying to transfer the title of a moped from Ohio to Michigan. Workers told him that if he didn't have the title with him, they couldn't help him. He did not have the title with him, police say.

The man reportedly got angry and threatened to "blow the place up."

Police say the suspect had left before officers showed up. At this point, although police are trying to determine the credibility of the threat, they say it "sounds like an angry person making a statement."

The Secretary of State branch is closed for the day.
