MIAMI (AP) -- The FBI is offering a $5,000 reward for information leading to the identification and arrest of a South Florida man dubbed the "ninja robber."
Authorities said Wednesday the man has held up at least 11 businesses in Miami-Dade and Broward counties. Store surveillance photos show the man usually carries a semiautomatic handgun and points it at store employees, demanding money. One female clerk had the gun held to her head.
Police say he frequently wears a dark ninja-style mask and clothes.
The businesses targeted have been convenience stores and gas stations. One North Miami Beach food store has been hit twice by the man.
Anyone with information should call the Miami FBI office at 305-944-9101.
