Security guard fatally shot outside Fla. bank

A security guard carrying cash from a South Florida bank to an armored truck was gunned down during a robbery Friday.

One suspect was caught, but at least two others believed to be armed were on the loose after they crashed their getaway car and fled on foot.

Several schools in the area were put on lockdown. The neighborhood was sealed off and teams of officers with dogs conducted searches. A sheriff's helicopter also flew above the area of the bank.

"They are armed and very, very dangerous," said FBI Special Agent Michael Leverock of the suspects still at large after the robbery around noon at the Bank of America in Miramar.

Authorities haven't released the name of the slain armored truck guard who worked for Brinks. The guard was heading toward the armored truck when he was approached by two men, Leverock said.

Leverock said that the guard was robbed and shot and killed on scene. A second guard was not injured, he said.

Brinks is offering a $75,000 reward to anyone who comes forward with information leading to the arrest of the remaining suspects. The reward offer is only good for 10 days.

Authorities wouldn't say how much money was stolen.
