The man is believed to also be responsible for the Feb. 1 robbery of the same TCF Bank, along with two robberies of the TCF Bank in St. Anthony.
He may also have robbed other banks in the area, authorities said.
The Thursday morning robbery began when the man threw a chunk of asphalt through the glass door of the bank at 8020 Hwy. 7.
He then vaulted a counter and entered a back room where employees were working, according to the FBI. The robber pointed a black semi-automatic handgun at the workers and ordered them to the floor. He then made them put an undisclosed amount of cash into a canvas bank bag and left.
A dye pack in the money bag may have exploded after he left the bank, leaving red dye on the suspect's hands.
