South Florida's so called "ninja robbers" were denied bond in their first appearance in federal court.

Clifton Lamothe and Michael Gonzalez are believed to be behind more than a dozen robberies, many of which were caught on camera, across Miami-Dade and Broward Counties.

The two were arrested last Friday during a traffic stop.

Both Lamothe and Gonzalez served in the U.S. Army as specialists.
