Developing: Authorities in Florida are searching for three robbers they say kidnapped a Florida bank employee, strapped an apparent bomb to his chest and used him to steal money from the bank.

FBI spokeswoman Judy Orihuela said a teller was abducted early Friday morning by three suspects and forced to help them rob a Bank of America branch in Coral Gables near the University of Miami.

The teller was wearing a vest police believed was a bomb.

He later was brought out of the bank unharmed. Orihuela says the three suspects got away with an undetermined amount of cash in the teller's late model, red Ford Mustang.

Police were working to neutralize the explosive device at a remote location, local station WSVN reported.

No other employees or customers were held hostage.

The school alerted students and staff to the situation and urged them to avoid the area but continued to hold classes. Some local elementary schools were locked down as a precaution.
