MINNEAPOLIS (WCCO) — A 49-year-old man has pleaded guilty to robbing TCF Bank in Uptown at gunpoint, according to the United States Attorney’s Office.

Brady Anthony Johnson, of Minneapolis, pleaded guilty to one count of bank robbery. Johnson was indicted on April 9, 2012.

According to a complaint, on March 28, 212, Minneapolis Police were called to the TCF Bank on the 1400 block of West Lake Street on Wednesday on a report of a robbery. When authorities arrived, a bank teller told police that Johnson entered the bank and approached her window.

She said he told her it was a robbery and to “Give me $100s, $50, $20, $10, $5, $1, do what I say.” Johnson implied he had a gun with one hand in the pocket of his hooded sweatshirt that appeared to be holding something, according to the complaint.

The teller told police she believed he would harm her if she didn’t comply with his demands. The teller gave Johnson the money, some with a GPS tracking device, and he fled the bank. Johnson was tracked by the GPS to a bus and arrested.

Johnson later told police he knew he was going to jail for a long time because “I know I robbed the TCF Bank,” the complaint states.

Johnson faces a potential maximum penalty of 20 years in prison. His sentencing date has not yet been determined.
