Authorities on Florida's east coast arrested a man in a wheelchair who they say robbed a credit union on Merritt Island and hid the money in his prosthetic leg.

Brevard County deputies say a 45-year-old man was caught Friday afternoon about 10 minutes after they say he robbed Space Coast Credit Union. The man is a paraplegic who uses a motorized wheelchair.

Investigators said he came into the credit union about 4 p.m., told a teller he was armed with an explosive and demanded money. He left with an undisclosed amount of cash.

The man told deputies that two people had threatened him with a gun, told him to commit the robbery and were going to take the money for themselves.

He was charged with robbery, grand theft, threatening to use a hoax explosive device and aggravated assault.
