A man, suspected in a recent string of bank robberies, is believed to have held up another bank Friday while in disguise.

Authorities say that the man was wearing sunglasses and a fake rubber nose when he held up a Guaranty Bank in a local Rainbow Foods store using a semiautomatic handgun, reported the Star Tribune.

The man is suspected by the FBI to have robbed at least four other local banks and is believed to have robbed a TCF Bank in a Cub Foods in Fridley, according to police Lt. Mike Fossum.

The robber has been dressed similarly in each incident and on Friday was seen wearing a dark blue suit, white dress shirt, cuff links and a driver’s cap.
