The FBI is trying to determine whether a man suspected of bank robbery in southern Minnesota is the same man involved in a string of heists around the metro area. Authorities arrested the suspect after a bank robbery in Brewster, Minn.

Mark Wetsch is charged with robbing a bank in southwestern Minnesota's Nobles County, but investigators suspect he's behind the long string of heists attributed to "the Man in Black." Officials believe that robber - whose wardrobe eventually diversified - may have held up banks in a dozen communities.

The latest robbery happened late Wednesday afternoon in Bloomington. The FBI believes it's the same suspect involved in a string of bank heists across the metro in the past several weeks.

He's changing his wardrobe but can't shake the label. The FBI thinks the suspect in a St. Paul bank robbery on Wednesday is the same person behind a string of heists around the metro. This would be the robber's eighth bank robbery in two months. Needless to say, if you have any clues about the suspect, authorities would love to hear them.

The FBI is searching for a suspect who demanded cash from a Prior Lake bank around noon Saturday. The FBI says the suspect is 5-foot-8 or 9, mid-20's, and evidently suffering from a head cold.
