The Jacksonville Sheriff's Office said the man, whose identity was not released, attempted to enter a Fifth Third Bank branch in Arlington through a side door around 4:30 p.m. Monday, but he was unable to get into the building because it was an "exit only" door locked from the inside, WJXT-TV, Jacksonville, Fla., reported Wednesday.
The sheriff's office said the man, who was wearing a bandanna mask over his face and had the hood of his sweatshirt pulled up over his head, was armed with what appeared to be a handgun.
The suspect attempted to flee on his bicycle, but was stopped and taken into custody by a police officer.
Police said they have not yet determined the man's intentions at the bank. It was unclear whether the object he was carrying was a real gun.
