DEERFIELD BEACH, Fla. (AP) - The FBI is offering a reward up to $25,000 for information leading to the arrest of a man who shot a customer during a robbery at a South Florida bank.

Authorities say the man jumped the teller counter Wednesday at the Amtrust Bank in Deerfield Beach and took money from several drawers. As he jumped back over the counter, authorities say he shot a 67-year-old customer before fleeing in a pick-up truck.

The customer remains hospitalized in critical but stable condition.

Authorities say the man also is linked to an Aug. 13 bank robbery in Boca Raton.

The FBI, the Broward Sheriff's Office and the Boca Raton Police Department are investigating. They say the man wore a black baseball cap, sunglasses and a bandana over his mouth and he carried a black backpack and a small handgun.
