The FBI is investigating the second bank robbery in Coral Gables in four days.
A masked man robbed a Wells Fargo branch on Ponce de Leon Boulevard about 9:40 a.m. Monday.
FBI spokesman Jim Marshall said the robber entered the bank, implied he had a dangerous device of some type and demanded money from an employee.
There were customers inside the bank at the time, but no injuries were reported.
The man got away with an undisclosed amount of money.
Marshall said the FBI believes the robber is the same man responsible for Friday's robbery at a nearby Chase branch.
Anyone with information is asked to call the FBI office in Miami at 305-944-9101.
