OAKLAND PARK, Fla., July 24 (UPI) -- Authorities in Florida said they are searching for an would-be armed robber who apparently showed up too late to steal from an armored truck.

The Broward County Sheriff's Office said witnesses reported seeing an armed man run up to a Brinks armored truck Friday morning outside of the Bank Atlantic in Oakland Park just in time to see the truck drive away, the Miami Herald reported.

Sheriff's spokeswoman Veda Coleman-Wright said the Brinks guards inside the truck did not even realize there had been an attempted robbery. Police were called by a bank employee who saw the man run toward the truck.

"(The guards) had loaded up and were getting ready to go and were pulling off when the robber tried to rob them," Coleman-Wright said. "They didn't even realize robbers were trying to rob them."

The sheriff's office said the man was seen fleeing the bank in an older model red Cadillac.
